Definately get a good picture of before. I've lost a lot of the weight and went back into my photos to find a before picture so I could see how I looked. Dang, I forgot that I didn't like to have my picture taken and didn't take many, I'm hiding behind the group with just my head in the picture or I'm the one taking the pictures.
I have a couple of snapshots from other people from the cheapy old fashion film cameras, they don't scan well and you have to have a magnifying glass to see.
So long winded way of saying, Get a good picture of what you look like now! From the front and side, wearing something tight so you can see the curves. Not you favorite baggy shirt and shorts. Then once you start to lose the weight, keep the fat picture of you as motivation not to ever look like that again. Food is not worth it....as I try to convince myself of that when ever the people at work bring a pizza in. Sometimes it works other times
