What site does everyone use to host their photos? I do not want to buy my own webspace, but would prefer a website like flickr or google's picasa to host my best shots. I am just looking for a no hassel free site to post the best pictures I have taken, not the entire quantity of them. I should probably add that I am going to buy a MB or MBP after MWSF. Should I just hold off until I get a Mac and use iPhoto?
