What image viewer for Touchscreen??
 

I have an app that (among other things) displays pictures from a database. In terminal mode, we've been using zgv, and in X mode, xzgv.

Basically, the scenario is that the user scrolls through data and when he wants to see a picture, presses a keyboard key; the picture is displayed; when he's through viewing the picture he presses ESC key (for xzgv, presses Q).

We're implementing this on a touchscreen system with no keyboard. So instead of keyboard keys, the user will press "buttons" on the screen. The part that's a little touchy is where he's done with the picture and wants to dismiss it.... he can press the X in the upper right corner, and that works, but it's pretty damn small, and not that easy to get a fat finger on.

Sooo... what we need is a way to make a bigger "done" button on the picture, or some other way for a "big-enough" button to be used to close the picture.

Any ideas?
