I feel for you. I do. When you're not at the weight you want, you don't want a camera coming anywhere near you. Getting your picture taken can make you feel unbearably self-conscious, but when it comes to losing weight, seeing what you look like can help you make progress.
Wherever you are on your weight loss road, start today, and take a picture of yourself. If you're up for it, take a picture in a bathing suit or your bra and undies. Don't worry because these are pictures only you will see. As you continue with your weight loss/fitness program, take a picture of yourself every week (or every month like they did in this photo from the September 07 issue of Allure magazine). After a couple of months, you can line up all the photos in a row and actually see your progress. It's truly amazing to see your body transformation in print, since you don't necessarily notice any changes when you're looking in the mirror everyday.
Seeing your weight loss documented like this is also a great way to motivate you to keep working hard. When you can actually see how your efforts have paid off, you're more likely to keep at it.
