Take any picture, size it, and print it on a laser printer, then iron it onto the shirt.
It doesn't sit on the surface like those old cheap Tshirts, it melts right into the fabric.
I did one for my daughter 3 years ago, and she's still wearing it and it looks fine. I've done B&W line drawings and full color photos.
That sounds alot like the transfers I use. We have a commercial press, and the shirts come out real nice.
I found one Lipizzane (sp:) in one of the catalogs but on line it says it's been discontinued. 9000 transfers and none like she is looking for...I'm not trying to spell it again:).LOL
