Eh.
Sprint's picture mail kinda blows. It's crazy inconsistent for me (only seemed to work if pics were resized to 640x480 and it still failed from time to time), and really slow compared to email, so I kinda gave up on it.
I tried Shozu, and that worked alright. I didn't like how it crashed Worldcard, but if you don't use worldcard then it's fine.

My solution was to use Flickr and Switchabit. You can get a dedicated Flickr email address (which I named "flickr upload" in my contacts), so I send the pic to Flickr in an email. Then Switchabit automatically transfers the pic to Facebook for me. The lag is never more than a couple minutes.
