Yes, when I send a pic via the Arcsoft mms account I can go to
http://pictures.sprintpcs.com log into my picmail account and see the pictures that I have sent/received to/from my friends. I can also take part in all the other features just as if I had a ordinary camera phone from sprint.
Not sure if this is the answer you are looking for....
Just in case.. no, I do not have to upload to the picmail site and then send from there...though I could
