[WikiEN-l] Application of the {{pd-art}} tag

I didn't have any luck getting an answer to this on the wiki, so I'll try asking here. I've been using the {{pd-art}} tag for Greek vase paintings I've uploaded, but before I really go hog wild and start uploading these on a large scale I'd like to be sure that this would be a good idea. So, two questions:

1. Are we relatively sure that the Bridgeman Art Library vs. Corel Corp. case applies to two dimensional art on a non-flat surface? I've seen other users use this tag for that purpose, but I don't know that any of them were any more informed about this than me.

and

2. Since that case was a strictly US case, are there likely to be issues with downstream usability of these images outside of the US?
