I use it almost every time I'm looking a Screencapture from a Certain Movie or a Poster. I always try to add the right tags to a Image to it's easier to find.

If I'm looking for something specific. Sometimes I'll just feel like browsing, and I won't bother with a tag filter, but if I'm looking for a picture from a certain movie or of a certain character, then yeah, sure!

Same goes for all the other Fanpop clubs I'm in. That's why I think it's so helpful if people remember to tag stuff - makes it so much easier to find and appreciate. :)
