It took me a while to do, couldnt figure it out even with some members pm me with info. I went to weatherunderground.com and went to the weather sticker section. From the long azz banner info it gives you, I had to copy a paste only a portion of it so that it would work when I put it between the  you get when you hit the mona lisa button up above to insert and image.
I intentially left some spacing between the img codes and the banner info I got from the website so you could see it. Good luck. Took me for freaking ever to figure out. Im not too learned on that type of stuff.  ;D
