Ahh, cool. I hardly ever visit the gallery unless it's to manage my own album. Would be handy for me if it was added to the pop-up window we get when we access it off a profile or from the Recent Uploads.
There is a report a photo link under every picture in the gallery. Using this feature promptly brings it to the attention of the GuildCafe staff. The same for posts in our forums and comments on pictures.
I never noticed, I'll use it next time I ever come across something of the kind.
