When you have the Desktop Objects Editor open, you can add an Image Object.

Here is a description of the general properties:

• Object Name - You can name objects for the purpose of selecting them in the combo box above.
• Image File Name - Select an image file to be in this object. A shortcut is to double click on the image object.
• Transparency - The current transparency level of the object.
• Pixel Operation - Selecting a pixel operation does the following:
  • Opaque - draws the current image with the transparency applied. For all other operations, the transparency does not work (not yet).
  • Add - Adds the current image's color with the color underneath it. Basically, dark colors become transparent.
  • Subtract - Subtracts the current image's color with the color underneath it. Basically, light colors become transparent.
  • Modulate - Somewhere inbetween the two above operations
  • Min - Similar to Add. It takes the min of the two colors.
  • Max - Similar to Subtract. It takes the max of the two colors.
  • Pattern - Generates a vertical line pattern.
