You could actually use a different folder for your images. The hard part actually would be that you would have to do a lot of work on your end to do it. These files have been there a long time, and all the relative links in UBB would point to them there. So you would make a new folder, put your images in, and you would have to add more relative links to the new folder(s) in your UBB script in order for UBB to know where they were. It would not be an easy task in my opinion.

This said, as I am writing this, I am not an expert. I would recommend asking one of the more savvy guys like SD, Gizmo, Ruben, or gliderdad, as they are probably the most familiar with something of this caliber.
