Hi Derrick, 
 
The only solution I've found to post pics from my iPhone or iPad is not with the Safari browser, but with a different browser called iCab Mobile. There might be other alternatives and/or solutions, but I'm not a geek, so I wouldn't know  
 
Buy the iCab Mobile app and you're ready to go to post pictures just like you do from a computer. 
 
Hope it works for you! 
 
Cheers, 
Petra
