you know my answer
check manually if the information is there....
95% of tgp's have silly link limits.... eg: 6 outside links, requiring 3 recips....
When I autogenerate my galleries, I don't have a link.. I have text at the bottom stating where it is.... from what I've read, that's a pretty standard way of doing things...
besides, as far as i know, as long as you don't have hardcore thumbs, you're not required to maintain 2257 info on the galleries you link to...
but, I'm Canadian.. soo.. I don't really know too much about 2257, nor care
