Maybe I'm an odd one, but I really tend to like pictures of myself more than I used to, even as I've gotten fatter. I think right now a big part of it is
knowing that I'm putting effort into my health and physical fitness, so in a way, I feel like that makes me look so much happier in photographs than the miserable in-denial, self-hating person I used to be, even when I weighed a lot less.
I think another big part of it for me is that fact that at some point not-so-long-ago I decided that just because I'm fat doesn't mean that I can't put effort into my appearance and dress more feminine while I work on chipping away the 120+ pounds I want to lose. I think maybe my brain picks up on the positive changes in my appearance (thinner face, make-up, slightly longer hair) when I look at pictures rather than dwelling on the negative (imperfect skin, still over 100lb to lose, etc) because it doesn't want to sabotage my efforts with negative self-perception!
What I'm really angling at is that when I look at pictures of myself now, I'm not 100% happy with what I see by any stretch of the imagination, but I am proud of myself for where I've gone and what I'm going. Besides, I'm sure I'll love having my fat pictures around to compare my goal pictures to once I'm finished losing weight!
When you look at pictures of yourself that you aren't particularly fond of, try forcing yourself to focus on one or two things that you are proud of or do like about yourself and focus on those and try to remind yourself that you've lost almost 25 pounds, that's nothing to scoff at!
