How To Import Patterns Onto Characters

I have a muscular character wearing a tight shirt, and I’m trying to use a 2D JPEG or SVG image as the “color” of the shirt. That is, it’s a JPEG (also tried SVG) of a photograph I took. The image is to be wrapped around the character’s shirt.

However, the only tutorials I can find talk about placing images on planes, which is useless for me. Does anyone know how to do this? I would have thought it would be straightforward.

If you’re talking about projection painting/texturing then here you go a link to that. But otherwise you’ll have to be more specific of what you want. I’m not so sure if you could wrap a picture around a characters shirt, that wouldn’t turn out so good for your characters shirt.
