You're asking for trouble using categories in your URLs. It shouldn't affect
the issue you mention below, but I recommend against this pattern if there
is any way you can avoid it. WP is not well designed for for category based
post urls compred to dates.

Have you considered using "Pages" instead of posts? It looks like that would
be a logical way to organize your collections of paintings and prints and by
making them children you'd get your desired URL structure.

That looks like it should work. Did you try print_r($categories) to see
what's inside?
