Better image picker (gallery style), please

[derei]

Instead of media picker, which opens the file manager, it would be better to use a gallery style image picker, I believe.

Also, the buttons for media loading, share, undo/redo, would be better placed at the top of the screen, for a cleaner and more intuitive interface.
