I just got a Mac (first time) and I am unable to upload my photos in batches to my photo processing website. The program is called "quick upload", but neither york nor snapfish (same interface) prompt me to install it. I tried in both firefox and safari, and no pop up blockers are enabled. I found a plugin for Walmart photo center (for mac). Downloaded and installed it. Works for walmart, but not for york. I am new to all things Mac so I would appreciate if an expert out there could steer me in the right direction! Thanks.
