The flickr account thread reminded me of a question I've been meaning to ask.

Does anyone here know how to replace a photo on flickr? A bunch of mine where edited before I calibrated my monitor and some look pretty bad. I'd like to be able to just upload a new version and keep all my tags, descriptions, comments, etc.. I know I can just delete a photo and upload a new one, but I'd loose all that history and things would get out of order. Just wondering if it's possible.

Thanks,
Paul
