GoFuckYourself.com - Adult Webmaster Forum - Anyone had any publishing / photo royalty experience?

Might be an odd forum to ask this, but in any case:
Recently contacted by a publishing firm wishing to use one of my photos for a cover of an upcoming novel.

I've got no idea what to ask in terms of demands / royalties / whatnot.

Seems it's not going to be a massive run, nor an expensive one..
