We have added a feature called Zoom+ , so now all pictures larger that 575x  will have a new feature which allows them to be able to use a Zoom function on the picture and enlarge all details of the picture. It works by moving your mouse over an image to see an zoomed version of it. It places a square to the right of the image with the magnified portion of the image. This feature will only work for pictures uploaded on or after 5/22/2012
