i used to paint all the time, Jack, but this was back in the 80s. i was told way back then that it was it was NOT a copyright infringment to paint using someone's photography. and i was told it was not necessary to obtain permission. i never researched any of this myself to make sure my source was reliable, however. i was just a young kid and i guess just trusted that adult who told me. i think Richard made a good point to ask this question in the copyrights forum. i would rather be safe that sorry. personally, i would have no problem with someone making a painting from one of my works. but asking is nice...and as doug said, if you make millions from it, giving the person who inspired you a % would be a nice gesture. i like that you do give credit by saying "inspired by."
