Photoshop CS6 13.0.4 - when I save for web, change to JPEG from GIF, save all slices, the first and last slice are saved as JPEGs and the rest are saved as GIFs. Why on earth would it do that? I'm running on a Mac 12-core, 40GB RAM, OS X 10.8.2.
While I'm here, I've got to mention this: This thing where, every time I do my Save for Web, it tells me that my image is much larger than Save for Web was meant to deal with -- this is REALLY annoying when I have to save 50 slices one at a time. I KNOW the image is bigger than that; do you have to tell me EVERY TIME?? Why isn't there a way to shut that off?
That's what I thought, too, so I tried it a few times, making very sure that everything was selected and all of the settings were what I wanted. I get the wrong thing for all but the first and last slice, so now I'm stuck saving a zillion slices manually.
This used to work, so I don't know why it changed.
