I have successfully created and posted several showcase slideshows with thumbnails. Recently, I re-sized the large images in showcase, saved it as a .spg, experted to FW, then opened FW and replaced the showcase gallery file with the new one. The large images appear and all the buttons work, but the thumbnails only show as empty boxes. If I click on the thumbnail boxes in preview, they will display in the large image size but not the thumbnail size. What am I doing wrong? If I select either of my old galleries, they work fine. I have also done a 5.5 pro update and no change.
