can no longer post pics...help

anyone foolish enough to read any of my posts know how much I enjoy posting photos...mostly useless, no purpose, sort of like where the direction any of the posts lead to...like this one...anyhow...lately I've been experienceing problems trying to copy from my photobucket album and post on any thread...something that was always so easy to do. You know...find the picture...hit copy and then hit paste on thread...and bingo...done...doesn't work anymore. Any suggestions other than to thank the photo gods from my not being able to do this anymore...and of course not pointing any fingers in the direction of any certain gender but considering the amount of certain select female photos often in the theme that leaves men finding a need to lower the seat, wouldn't be surprised they figure into this problem I'm now experiencing...so...any ideas would be appreciated.
