I am using Photoshop CC 2014 on OSX 10.9.5.
I can set the loop count to be a number greater than 32 from within the timeline panel, but when I get to the Save for Web screen, it changes the looping options to Other(32). If I try to manually change it to > 32 on the Save for Web screen it tells me a value between 1 and 32 is required.
Why is this limitation here? If I use a tool like Gifsicle I'm able to create > 32 loops.
