So I bought photoshop and I tried making a sig, but whenever I get a picture I want to use theres a giant white box sourrounding it. how can I get rid of this? and is there a way I can get pictures that come without the white box?

i sometimes use the magic earaser tool but it doesnt work sometimes or u can just make an account at www.planetrenders.net and u get free renders without the white
box.

its called rendering, either use pentool to cut out the pic then erase white parts to clean up, or if u too lazy
go to planetrenders.com
