Here's a sample image that is 5287x713:
Clicking on it will give a larger view, but the size is limited to the size of the browser window:
The above image is larger for sure, but the content still can't be read. The full size image looks like this:
So clicking an image would work like it does now. But clicking that enlarged image should then push the image to it's full size and be in a "window" that allows panning and zooming.
The full image is already uploaded, but I wonder if most people realize the image can be viewed in a larger size by copying/saving it, then opening it with an image editor. Re-clicking an enlarged image now returns it to the smaller size.
