/3/ - 3DCG

Is there a utility or something to help me with 2d texturing out there?

I'm doing this arm tattoo for one of my characters, but as you can see in the pic there's an obvious aberration where the texture seam is. Basically, I'm wondering if there's an easy way to resolve this business, like if I could paste the tattoo picture directly onto the body and have it generate textures from there. I'm pretty sure that's how they do it in the vidya industry.

I could spend an evening in photoshop fixing the seams but if there's an easier way, I'd love to know!
