Do you mean that the source of the link is an image rather than a web page or that the target file is one of your images rather than the web page on which it is displayed?
I don't know of any way to link from an image except to put the img tag between anchor tags which would show the source as the page not the image.
Linking to an image is no problem, you can link to any file type not just web pages. It is something that I see done fairly regularly in some forums.
