How to make a draggable image?

I have a frame, and in it I have a very large imagelabel. You can only see a portion of the image at any one time. I want to have the user drag the image around to see different parts of it. Just like one would drag a map in Apple Maps. I tried simply making the image "draggable" but that did not seem to have any impact when I run the program. Ideas?

Thank you.
