not as far as i know, there's been a couple of threads about this on here, have a search for fxp. if you have shell access on your hosting account there is nothing stopping you from ftping to all your sites if you enjoy writing a good shell script come to think of it you could probably get something working even if you didn't have shell access.... But batch ftp uploads from your own machine, prostockmaster et al, picniche or isyndica costing like 1c per image it's all a lot of effort for not much gain/saving?
