I store the photos that I use for some of my contacts in a folder called Contacts I made on the media card.
Anyway, the problem I have is when I assign a photo to a contact, if I edit the contact in any way after the fact, the photo gets unassigned and I have to repeat the assigning process.
I realize it's not the worst thing that can happen on a Berry and is certainly not the end of the world. Still though, it's annoying.
