A very good bannerless free host is
revshare hosting . They pay full price for almost all there sponsors plus a little bit less for some - ARS they pay you $30 per signup instead of $35 etc.
A good way to start so that your friend can try and experiment with different types of traffic without having to worry about the huge bandwidth bills that can accumulate right from the start - plus they also have thousands of free pics to use - I think they are now up to about 200 different sets.
allright
