Current design:

==========

When we preview the images of email attachment, we need to preview it one by one now by closing the previous window, then open another window. this experience is not very good.

Ideas:

==========

A more reasoble experience should be:

1. When we preview the image, there should be "Previous" and "Next" button available, so that we can click corresponding button to preview all images in one window.
2. Some basic image processing should be supported like Zoom in, rotation ( because sometime the image was in reverse direction).
