HTML tags only change the dimensions of the image. To change the size, you'd have to save it and lower the resolution. I managed to get it down to 50k, but you posted just before I had the chance to. =p
Hmmm, that's more of a hassle than I realized. Gotta save the picture, reduce the resolution, upload it to a new host, and then link. No wonder I beat you to it. No telling how many computers I crashed.
