How to program previous and next pushbuttons?

Whoever can help me, kindly find the attached screenshot of the GUI I created so you can understand what I exactly need. The first axes has a set of images and so does the second axes, the second set of images function as the results of the first one, so what I need to do is to be able to shuffle between them both at a time, using either previous and next pushbuttons or a slider, I'm new to matlab and GUI, and I can't figure out how to have this done. Can anyone please help me through that? Thanks so much in advance!

One way is to create a global variable that both button callbacks can see and you use that as the index into a list of images that you display. Then you increment or decrement the old index (depending on whether the next or previous button, respectively, was called) and call a function AnalyzeSingleImage(index) with the new/current index. In that AnalyzeSingleImage() function (which you need to write), you display the original image in the left axes, display the processed one in the middle axes, and whatever you want in the right axes.
