I wish the LJ User Icons could be HTML links. Then I could make my icons links to the source of the icon's image. I would feel like I was advertising the artist, rather than stealing. I've collected a lot of
images that I might someday like to use as icons, and I'd like to give credit. Some of the images are on
CafePress, or are items for sale elsewhere on the web, so linking the icons back to those sources would be convenient product placement -- if you really enjoy the image, you can buy the object.
[EDIT] Please do check the comments for this!
