I find that I'm often asked to share lots of photos with someone, enough that uploading each one individually to them gets tedious when I would like to drag and drop the whole bunch. I could put them on photobucket, but some of them are semi-private; private enough that I don't want them to be easily found on image hosting sites.

Are there any convenient ways of sharing these photos quickly but still being able to remove them from the inter-webs afterwards (without too much hassle)? I have found Yahoo Messenger complete version has great photo sharing options; but not everyone has it and I can't expect people to download it just to see some photos.
