fred,
go to http://www.imageshack.com/. upload your pic there and link here. just copy and paste. it's free and they don't send you a bunch of ads and crap either. it's real easy.

www.jeeppages.com is cool too but you can only put pics of jeeps in your album and it's not quite as simple. there are tons of others too but those are a couple free ones i have to host pics.
