For a background and on the edges of the picture, I think Ice might be easier to do(?) but how? and ofcourse I dont want to forget of adding the effects over etc. on the main character in the picture, which will be shown to everyone when I manage to cut it off of it's current background.
Please help me, you're my only hope.
**** EDIT ****
For a signature or a desktop wallpaper, both work.
