When I click on that picture, and click on it again, it's still not full screen...even on my laptop.
It's also clicking twice instead of clicking zero times for me. When folks upload pictures here, I won't even click on them unless it's something I'm really interested in.
I'm on here using two different laptops, two different desk tops, a phone and two iPads and I rarely have a problem seeing pictures that folks have hosted on Photobucket.
The problems with pictures disappearing aren't normally because Photobucket did something. It's when folks delete them, move them to a different folder, or delete their account. I'm not a fan of Photobucket as a company, so I'm not defending them, just stating that picture loss is usually an error or ignorance on the part of the user.
Honestly, I don't really care much one way or the other. This thread has gotten to the point it's almost useless other than for general "wow, that's nice" sort of viewing. There's no reasonable way to search it, and after 50K posts, it's too long for folks to really go through it.
