Hello!

I’m curious if anyone knows of a plugin that can do what this site does?
http://bang-on.com/t-shirts/nerd-alert/better-call-saul

Ideally if I didn’t have to save dozens of images and I can just super impose the t-shirt color under the design? I hope this makes sense. I sell t-shirts but the designs are not changeable, just the color of the shirt and it’d be nice if the user can view the different colors available with the actual design.

Any ideas and suggestions would be awesome.
