Design Question

I think this is the right board for this. I have a question about a design program. I'm wondering what program is used to make the sales banners that many of the SEO package dealers use. The ones with the different brands/movies/cartoon type designs with the different packages.

I'd imagine photoshop/illustrator or something similar if you want it to look fairly decent. Or paint if you want to do it for the lulz.

They are either skilled in Photoshop/Illustrator or hire someone to do it for them
