Hi, these are actually pretty tough questions. Gallery is really lacking some important functinality like event when the image actually stopped moving. I had the same problem and I "faked" it using Gallery.drawChild method where I am checking if the position of the image is in the middle and if the the gallery is touched or not (by setting simple boolean in onTouchevent). This works for me.
As for zooming - you can use either WebView or implement something like this: http://www.zdnet.com/blog/burnette/how-to-use-multi-touch-in-android-2-part-6-implementing-the-pinch-zoom-gesture/1847?tag=content;siu-container into this http://blogs.sonyericsson.com/wp/2010/06/09/android-one-finger-zoom-tutorial-part-3/ (you can read also previous parts to help understand it) BUT if you want to use gallery for sliding of fullscreen images (no an ordinary carousel) I recommend reading this article http://android-developers.blogspot.com/2011/08/horizontal-view-swiping-with-viewpager.html I've used it and made it work like a charm :) I hope I would have time to publish it someday. And for "progressive" rendering of the image - I'm using small thumbnail streched to the fullscreen (by maintaining original resoultion ratio!) and then just loading full sized image into it. It's not animated but animations are only causing more troubles and are "wasting" users time. I hope it would help you at least a bit. Good luck.
