How To Post Pics?/Rambling!

I know there is probably many topics on here telling me exactly how to do this, but I can't find them. I was wondering if anyone knows how I can post pictures and put a profile picture so that I am no longer a faceless person :P

I get surgery July 30th! (: I am extremely anxious, nervous & excited and I want to post pictures as I progress. 

By the way, I currently weigh 235lbs before 2 week liquid diet pre-op. Not sure if that'll change or not before July 30th. But I am 5'4... So if there is anyone out there who has had surgery at my height and weight that could tell me where they're currently at and how far out they are, that'd be amazing. 

Also any tips for me? Anything is appreciated, even if its right down brutal :P 

I am 5'1 and started out at 232, I am 11 months post op and have lost 92lbs. Everyone looses at a different rate and bosy types and frames are also different. I happen to be very compact and muscular and probably won't loose too much more (I am hoping for about 18 more pounds by the 18 month mark, but this may be along shot because that means I need to loose 2.62 pounds per month and I lost a whapping 3.6 pounds this past month). I am content with how I look, actually I am thrilled, loosing and maintaining another 8-9 pounds would suffice ("normal" BMI). There are some people who are several inches taller than myself who become very thin, under my ultimate goal, and had sometimes more to loose, and there are probably people who are close to my height with the same amount to loose, but have lost less. Weight loss is highly variable, try not to compare yourself to others throughout this process, trust me you will be discouraged.

For posting in forums (replies and new topics) if you have a MAC computer:

Upload your picture to your profile, open your new topic in a new window, then drag the picture from there and drop it here. 

Don't copy & paste - drag and drop. Open one window with the picture and another with the posting you're creating. 

If you click on the picture on your profile, hold it down and drag it to the posting. You'll actually see the picture being dragged when you do that.
