That's a very good point - each category could have a partitioned off section for "Images in this category" as seperate from "Articles in this category", with no extra work on the user's part.
I was also going to suggest that one benefit of having separate image categories is that they could be displayed as auto-thumbnailed galleries, rather than lists of links. I guess even this could be done within the existing structure - although it would become even *more* important to have a decent multi-page results system...
