By the way, I just tested it again adding a new gallery in Windows and then in Ubuntu — it works fine that way. But when my clients uploads new photos to the gallery through her Mac, all broken thumbnails. I am frustrated because we went through many different gallery options before she decided she wanted this one in particular. But if she can’t upload photos to her own galleries because she’s on a Mac, this is now costing ME money as a web designer because I’m liable for that and I’ll have to purchase a whole new gallery, configure it, and re-upload 300 photos. !!! Please help!
