So when you hover over the thumbnail the picture enlarges but doesn’t actually open unless you click on it.
If you have a few of these to do on a page, then the simple way would be with Target Show/Hide Layer (or Image) on the large images, and a matching instance of Rollover on the small images.
Do you mean I create the large images with the submit image action button? I was reading on this but can not find the action in my list. I tried to apply the rollover action to 2 of my images 1 small and 1 large and it will not work, action is not highlighted, not sure why?

No - you create a graphic (or layer) as you do any other item then apply the Target show/hide action to this newly created image/layer (this will be the large image)
The rollover is only applied to the smaller (trigger) image.
