Making thumbnail images movable by user

[IFU]

Does anyone have tips on how to make full-size images movable? After clicking a thumbnail image, our users would like to be able to drag the full-size image out of the way to see the text underneath the image.

I have seen this older post - is there any more recent information out there?

I may have found my answer - I think I can adapt this to images (fingers crossed)
