To post a picture here, it has to be 30kb or smaller. There are ways to make them less, some people know all the tricks. I' m not that good yet! The only way I know is to post your picture on one of the free photo sites, like imagestation, photoisland, etc., and then " crop" it, kind of cut off unnecessary edges. If you can get it small enough that way, it should work.
Maybe someone else can explain other ways of making it fit!
