When I used your edit at http://www.photopost.com/forum/1228868-post9.html
it still didn't work. When I used your edit AND turned off VBSEO, it worked. This didn't make sense as the replacements are perfect (triple checked). However, then I turned on the filmstrip at the bottom, and VIOLA, the filmstrip AND the next/previous links work w/ VBSEO. I'm not sure why enabling the filmstrip helped, but it definitely did.
I believe I turned off the filmstrip because it previously wasn't working with VBSEO.
