I would much rather have an image resize that gave me a choices like: thumbnails, small, medium, and large. I use this app to resize images to include in email and on documents, so the aforementioned sizes would mean more to me. As the app is currently, I keep going back and forth between the email and the resizing app until I get a size that works.
The slider that is used to select pixel size is annoying. Wherever I place it, by the time I pick up my finger, it has moved. No precision here at all. Let me set the several sizes that I use most, and I'll give this all 5 stars!
Also, "All Photos" should be at the top of the list, not the bottom.
I'd like to give the app more stars, but it's just too clunky.
