depends on what it's for.
if the website isn't using it for commercial purposes, i.e. they are nonprofit, then if you are willing to let them use, you shouldn't expect renumeration.
on the other hand, if they are profit-making, then obviously you have a right to demand, and point that out.
in every case, you have a right to demand renumeration, of course.
i have gotten many such requests, normally once you speak of renumeration they thank you and tell you to have a nice day and look elsewhere. :bsmilie:
btw, sometimes you even get requests from publishing companies, airlines, etc.. best part is, from experience, none of them are willing to pay.
why? they have been spoilt by the exploding amounts of overzealous people online who think that "exposure" is going to help them. not when the credit line is not placed prominently....
