Pano2VR 7.1 Docs / External Image

External Image

Use the external image to add images that need to be loaded externally rather than embedded in to the skin. This is especially useful if you have a lot of thumbnails in a tour and are not using the Node Image element.

Calling the images from an external source will help keep the tour running smooth rather. You can also embed a YouTube or Vimeo video. Content (URL) can be dynamically changed the content using a Set Value action.



The rectangle’s background.

  • Enabled Select to show the background of the text box.

  • Color – Use the color picker to choose a color for the background. ✭ Logic Block available.


The border or outline of the text field. Width, Radius, and Color of the border can be altered for the entire border or a single edge or corner. Click the Toggle Single Value/Separate Values button.

  • Width – Defines how wide the border will be.

  • Radius – Increasing this number will round the corners of the rectangle. Could be used to create a circle.

  • Color – Choose a color for the border. ✭ Logic Block available.

Image Border

  • Radius – Adjust the corner roundness of the image. This will show the rectangle’s background. Enter ‘999’ for a circle or ellipse.

External Image

External URL

Enter the image’s URL for externally loading the images. The URL can be a file path or a web URL. The paths should be absolute (full).


Unload content on hide – Selected, this will unload the content when the Image Loader hides. When swapping out content, this prevents the previous content from being visible before the next content shows (loads). If the content is not changing or being swapped out, then this can be deselected as it won’t unload and reload the content.

Content Scaling

Choose how the content will be scaled within the frame of the external image container. Choose from the following options:

  • None – No scaling
  • Min – The image will be resized to be as large as possible without clipping. Original aspect ratio is kept. May result in empty space on all edges.
  • Max – The image will be resized so that the entire area of the external loader will be used. May result in the image being clipped, if the image’s aspect ratio doesn’t match that of the external image element.
  • Horizontal – The image will be scaled to have its width fit the width of the external image element, maintaining its aspect ratio.
  • Vertical – The image will be scaled to have its height fit the height of the external image element, maintaining its aspect ratio.
  • Fill – The image’s width and height will be scaled to match the aspect ratio of the external image loader. This will distort the image if the aspect ratio of the image and the external image element do not match.

Never enlarge – Select to never scale the content up beyond its original resolution. Will not have an effect on SVGs as they are resolution-independent.

Clip content – When selected, the content will be clipped by the External Image’s bounds.

  • Scrollbars – When the content is clipped, you can choose to have scrollbars that allow the user to move and view the clipped content.

Alignment – Choose how the content will scale within the external image container.

Alternative Text

Alt Text – Add a description of the image for screen readers (accessibility).



Give the element a unique ID or name. An ID is given automatically and will be numerically ordered when more than one are added. If an ID is already used by another element, a warning symbol will appear next to the input field.

Point Hotspot Templates will have a menu that shows all the default template IDs as well as any template IDs used in the project.

★ Tip  Click the warning symbol to create a unique ID for that element.


The X and Y coordinates for the element.

An element’s position is relative to its parent and to its anchored position (the Canvas is the parent to top level elements).

For example, a video that is anchored and placed in the middle of the Canvas will have its anchor set to center and X and Y set to 0. So, if the element is anchored to the horizontal center, the X coordinate is measured from the center of the parent to the horizontal center of the element. Likewise, if an element is anchored right, the x-coordinate is measured from the right side of the parent to the right side of the element as indicated by the arrows.

★ Tip  Double-click the arrows to set X and Y to 0. This makes it easier to precisely position elements, especially on the edges of the player. For example, to keep an element positioned on the bottom center of the player and a certain distance from the edge, set the anchor to center bottom and set the Y value to 20 pixels and X to 0.

X and Y:

  • Percentage – Unit to set the position of the element based on the player’s size/window.

  • Pixels – Unit to set the actual location of the element within the skin.

  • CSS – Select CSS as a unit to allow for changing units when a logic block has been added or to use calculations.

    • Example: Set the x position unit to CSS. Enter, 100px in the edit field. Add a logic block, choose a trigger and add 20% for the size, effectively switching units.


Use this grid to “stick” the element to a section of the player window. See above, to learn how the Anchor influences Position.


The Hotspot Template and Node Marker do not have a size parameter.

Adjust the element’s size (width and height) in pixels. Width and Height:

  • Percentage – Unit to set the size of the element based on the player’s size/window.

  • Pixels – Unit to sets the actual size of the element.

  • Lock Aspect Ratio – Click the link icon to lock the element’s size aspect ratio when resizing in the Canvas or changing size values in the properties panel. This button is reset to off when another element is selected.

  • CSS – Select CSS as a unit to allow for changing units when a logic block has been added or to use calculations.

    • Example: Position an element 50 pixels from the top and then set the height to calc(100% - 50px). The element will then always have the same distance of 50px from the top and will extend straight down to the bottom.
  • Reset Size – Available for Image, Button, and SVG elements. Click to return to the image’s original size.

  • Reset Size/2 – Available for Image, Button, and SVG elements. Use this when you want to add a PNG or JPG to your project but still want it looking sharp in Hi-DPI displays. For example, if the skin requires a 32px image, use a 64px image and then click, Reset Size/2. This will then make it 32px in the skin but will still have all the pixels for a high resolution display.



Scales the element along the x and y axes. Doubling the value on either axis, for instance, will double the size of the element. If a scaling modifier is enabled, this scaling setting is ignored.


Use this grid to determine how the element scales. The default is set to the center so the element will scale in or out from its center. If you anchor the scaling to the upper left corner, for example, the scaling will center from this point.


Use this parameter to adjust the angle of the element. It will use the Center grid (above) as its axis. For example, if the center is chosen, it will rotate around its center. If the bottom left corner is selected, the button will rotate around that corner.


Select or deselect to keep the element visible or invisible. Visibility or invisibility can be changed and toggled with actions.


The transparency of the element. A setting of 1.000 is opaque. Lowering this number will increase the elements’s transparency.


Choose which cursor shows when the mouse rolls over the element.

Inherit – The element will inherit the cursor from its parent element. This is the default for all elements except Button and Seekbar.

Hand – The hand cursor will show. This is the deafult for Button and Seekbar elements. When selected, the cursor is not inherited from its parent element.

Default – Choose this option to force the browser’s default cursor (usually an arrow). When selected, the cursor is not inherited from its parent element.


Tab Index

To make skin elements controllable via keyboard, they have to be added to the tab order of the web page. A tab index of -1 (the default) excludes the element from the tab order. A tab index of 0 includes the element in the tab order. Browsers will highlight the active element by putting a rectangle around them. Once a skin element is the active element, indicated by the highlight, hit the Enter/Return key to trigger its click action.

ARIA Label, Description, Details

These are attributes or propterties that are used to define the element and support the Role.

Label – Defines or names the element.

Description – Provide a brief description of the element.

Details – Provide an extended, detailed description of the element.

ARIA Roles

ARIA Roles are used to define UI elements (button, loading bar, etc.). Choose from the list which best defines the element.


Select to hide all ARIA attributes.



Set the CSS z-index property. Use numbers to set the stacking order or leave the setting at Default. Default will use the stacking order set in the Tree.

This is used to ensure that elements are displayed in the correct stacking order especially when close or overlapping.


Select to make sure the element does not accept mouse clicks. This is useful for when you want to include an element in the skin but don’t want it to hinder the ability to interact with the panorama. For example, you could add a vignette or logo or border that when clicked on, will allow interaction with the panoramas.

Hotspot Proxy ID

Enter the corresponding ID. The ID comes from the hotspot’s ID field in the hotspot properties. Hotspot proxies give you the ability to link skin elements to specific hotspots. This means that the element will receive the same mouse and touch events as the hotspot (mouse click, mouse double-click, mouse enter, and mouse leave). You can also add {} to use node ID as hotspot proxies. Learn more.

CSS Classes

Enter the CSS class names for the selected element. You can enter more than one class separated by spaces. If you need more space, click the Edit button to the right of the field for a larger text field. No dot . needed.

CSS Styles

Enter the CSS style attributes for the selected element. You can enter more than one style separated by semi-colons. If you need more space, click the Edit button to the right of the field for a larger text field.

CSS Styles Inner Element

Enter CSS style attributes for the selected element’s inner element. (Some skin elements, like Image, Video and External Image, have an inner element nested inside the element’s main <div>.)

For example, an image element can have a border: border-radius: 20px; border: 5px solid red;. This can also be entered with a line break: border-radius: 20px; border: 5px solid red;

Keyboard Shortcut

Enter the preferred key to control the action defined to the element. For example, select the text field, hit the up key on the keyboard. Then add a Mouse Click action. The element, when clicked or when the up key is pressed, will perform the assigned action.

Exclude from Translation

Select this option to not include this element in the skin’s translation file.

Safe Area

Available for the Container Element.

Select Use Safe Area for Position and Size to keep child elements of the container inside the safe area of the device. This option makes sure that the elements are always 100% visible and the skin will automatically react to the device’s safe area.

Make sure Ignore Safe Area is not select in the HTML template settings in the Web Output.


Actions or a set of directions can be applied to any element added to the skin to create interactivity.

Double-click in the Actions area or click the plus sign to the right to open the Action Settings.

See Skin Actions, for details on all actions.


Adding modifiers allows you to make elements move, scale or rotate when the panorama is being panned, tilted, zoomed or loaded. A good example of a use of a modifier is for a loading bar that scales in relation to how much of the panorama has been loaded.

Double-click in the Modifiers area or hit the plus sign to the right to open the Modifier Settings.

See Skin Modifiers, for more details on all modifiers.


Use this section to add information about the element. This is especially useful if you have a component and want to explain the elements inside that component.

Notes will show up as tooltips in the Tree.
