Hello!
The first version that I installed and tested, picture viewer was scaling the image inside the frame. Now, this is not happening anymore and to see the comment area, Who posted, Delete Photo, Report Photo and share this, I have to scrool down.
I've changed the template to Beez3 and Protostar to see if it had something to do with my template, but the result was the same. I also activated the Bootstrap CSS in the Easy Profile Configuration page, but nothing seems to make any effect. As a matter of fact, the images are the same that I've uploaded to the Social Network Test Page, and there the images are resized inside the frame.
Attached goes an image of what I am talking about.
Regards.
