Image Specifications

Images are referenced by strings in the following formats:

• if a string starts with "http:," it will be recognized as a link to an ordinary external URL (Qubes 5.4);
• if it starts with "https:," it will be recognized as a link to an ordinary external URL (Qubes 6.0);
• if it starts with "stdico:," it will be recognized as a standard Qubes icon image (Qubes 5.6);
• if it starts with "folio:," it will be recognized as an image from a folio, in the format "folio:DocID/imageName" (Qubes 5.6);
• if it starts with "/," it will be recognized as a link to the current HTTP server's root (web process context: Qubes 5.6);
• if it starts with "." (or ".."), it will be recognized as a link to the current HTTP path (web process context: Qubes 5.6);
• otherwise, it will be interpreted as the name of one of the resources on the screen.

Examples for remote images

In the context of a web process:

• if you want to display the logo associated with the Qubes database, which is accessible at the root of QubesExpress, the Image property will be:
  "/COMPANYLOGO.QICO"
• if you want to display a background.png image defined in the Img element of the same web process, the Image property will be:
  "./Img?background.png"
• if you want to display a background.png image defined in the Img element of another web process, WP001, the Image property will be:
  "/WebProcess.cit/WP001/Img?background.png"
