Savings Picture from Main Profile Page

Maybe this is a known glitch, but pictures can be saved from an individuals main profile page.  I tested it on my own profile for safety/security purposes and discovered I could download the photo to my computer.  Thought maybe it was a one time thing, so I tried it with others to test and found out it could be done with more than a few.  Don't worry I downloaded, validated it worked and then deleted the photos.  I know that there have been disucssions about downloading photos from within a profile (the photos section) and that doesn't work.  Must be a gap in the coding that allows this issue.

Edited to add: Any picture on the main TN page - the highlighted profile, the recently joined/certified pictures, etc. can be saved.
