the best way would be start multiple accounts with multiple freehosts. you can fine tune the freehost to the gallery you want to submit.
for instance:
worldsex: go for
www.easythumbs.com - always accepted
al4a/ampland: go for
www.thefree1.com - always accepted
easypic: go for
www.freegalleryhost.net - always accepted
etc. just check out the big tgps and make a list which one accepts what freehost, and open accounts which are targeted at the tgp...
