Lost my picture. Help

I was playing around with my account and some how lost the picture that I had on my profile, which is fine because I was wanting to update that pic.  I cannot figure out how to get a new pic to show up can someone help. I also have seen the weight guides at the bottome of some of your postings, can someone point me in the direction of that.   Have a wonderful 4th of July.

GOOD MORNING  TO GET YOUR PIC BACK GO TO THE LEFT HAND SIDE OF PAGE AND SEE USER SETTINGS YOU CAN REPLACE IT THERE. ALSO IF YOU GO TO TICKERFACTORY.COM YOU CAN MAKE A TICKER THEN WHEN YOU ARE DONE PUT POINTER ON IT AND RIGHT CLICK AND COPY THEN GOING BACK TO THE USER PAGE ( YOU NEED 2 BROWSERS OPEN ) YOU CAN SCROLL TO THE BOTTOM AND ADD IT IN THEN SAVE, THEN WHEN YOU POST IT SHOULD BE ON THERE. I CHANGE MINE A LOT SO I JUST UPDATE THE TICKER AND PUT IT ON EACH TIME. YOU KNOW ME I LIKE TO BE DIFFERENT...LOL CALL ME IF THIS DOESNT WORK.. VICKI
