Long ago in Colorado i found a store that did copies. they had one of those large steam pressing machines like dry cleaners. i took them some fabric cuts i think i bought for photos to be put on and gave them actual photos from my camera and they put them onto the fabric for me. Like some people in shopping malls used to do for you only on t-shirts. I"m showing my age...
anyway my quilt was done and so far not been washed, so i can't comment on that part.
I found in swapping with many other quilters that you mainly need to "not" iron over photos. No matter how they got onto the fabrics. here is a pic of my older quilt.
good luck.
