Hey, I've been trying to make some comics recently with them sprites you get from MK warehouse, but whever I paste them onto a backround I get from the site, there is a white backround behind the characters that goes in front of the real backround which ruins the picture completely!

I've tried 'paint' and 'Windows Picture It!' but I can't prevent this, I also looked at the guides above but couldn't find anything - can anyone help me out with this? Just general tips on how you make comics would be really useful, thanks.
