Multiple pictures upload

With the new iphone OS 3.0 I can send multiple pictures (up to 5) in attachment via email. I'd like to publish the first picture in the list to single-photo-only web-apps (like twitpic), but i'd like to publish the whole batch to multiple-photo web-apps (like facebook, flickr, photobucket...). I hope you can make this one work out. It's a tough problem to crack, I believe.
