same thing here, if I browse someones gallery with the 'next' and 'previous' links I am able to hop to different galleries.

It seems like a problem with the links and the image numbers: each picture is named in the order that they are uploaded, no matter who uploads them.

So if you upload 5 pics in a row you would see those 5 pics when browsing in your gallery by clicking 'next', because they are named pic001, 002, 003, 004 and 005 for example.

But if you upload 4 pics to your gallery, and then someone else loads one, and after that you upload a fifth one again, browsing through your own gallery will show pic001, pic002, pic003, pic004, then the other persons image called pic005, and then your own 5ft pic again, named pic006.

Or so it seems. (former software tester here)
