How do I post pics on sp using only Iphone.

I need help posting pics using only iPhone

That is a good question.  I just tried to post a photo to sp using my Iphone and it appears that it can't be done.  I went to additional options  and the "attach" button was not active.  Not sure if this is a problem with the Iphone or sp.  I am curious if someone more tech savy than I am may have a solution.

you cannot imo...send it to your email and then save it on your computer and then upload...
