Tkinter image and scrollbar question

Hi everyone,

I am working on a module for my GUI that shows one image with an index value below and would use a scrollbar to control which of the images are displayed. The images are stored in a successive folder in the format Pic#, i,e. Pic1, Pic2 etc.

What I want to do is make a slider that is attached to a label which would output the slide number that is being looked at. I would use that number then to return the image of the slide to the TK window/canvas. I'm slightly succesfull using the scrollbar and loading images, however, I have yet to figure out how to do a simple scrollbar with a set amount of indices such as numbers 1-140 (which would be all of the pictures in the directory 1-n where n=140).

Here is some of my code, most importantly I would like to see a way of setting the slider to a preset beginning and maximum before I load the specific picture.
