Don't know about the pictures, but there is a way to deal with the multiple entries. It's been a couple of years since I did this, so I don't remember the exact steps. You have to do it from a PC, log into your gmail account and go to the contacts. Somewhere in there there is an option to merge duplicates.
If you don't find it I'll try to retrace the steps I took when I'm at a desktop in a day or two.
