Thanks, Felix. I've done exactly that and the set does reverse correctly, but the images on the website still don't reverse order. When I click on 'Photostream' the images are displayed in the same as order as the website (incorrect). When I click on the actual *set* (there is only one set) then the images are displayed in the correct order. All I can think is that sv is working according to the photostream order and not the set order. Is there somewhere within the code that I need to specify the set? I tried adding tags, but the order still didn't update. Also tried clearing my cache countless times. As mentioned I can update the caption text and the website updates instantly.

Here's part of my gallery.xml
