After a bit of experimentation I found a work around. This is for a PC. A Mac probably has a similar process. Click the picture to get the larger picture. Right click on the larger picture then select Open Image In New Tab. Click that tab then Ctrl-+ to enlarge the image. Each click of Ctrl-+ will make it larger.

Actually, a Mac is super easy.  🙂

Click on the picture to open it.

Then just put 2 fingers on the pad, and without clicking, just spread your 2 fingers apart horizontally until you've enlarged to where you want it.

Moving your fingers together will make it smaller again.

I have a touch screen laptop that I can do that on but for some reason it doesn't work on the enlarged images. It works on the thumbnails but that's just making a low resolution image larger. Can you say pixelated.

I was hoping someone would know how to bring up a + or - icon while looking at the pic in the forums. I guess this feature is just not exist.

Thanks for the idea of opening the pic in a new browser tab and Ctrl-+.
