First find a picture you want. Then when you have the picture on your screen right click it an go all the way down to where it says properties and click it. Another box is going to pop up. Now look where it says Adress(URL). It should be right in the middle. Now copy everything thats in the adress(url) starting with http and ending in jpg. Now to post your picture use this . so just follow that and it should work.
Well judging that he doesn't know how to post a picture then he must be pretty new, so don't be so harsh on him because I'm sure he didn't know any better.
