I've been suffering from the problem for a long time. A scrollbar is really very very important for inspecting large images.

Currently, when I'm looking at a large image, I have to re-scale the image, which means that some details will be changed. If I don't resize the image, I can't even see some part of the image.

I really believe this should be a basic feature for an image viewer for scientific purposes. If somebody would raise it's priority and work on it, I will be very grateful. Thanks.

Alternatively, if introducing a scrollbar is too hard, maybe we can add an option to show the status bar on the top-left of the window, so that one can at least know the basic information (position and RGB value) of the visible pixels.
