flickr, smugmug, alternative question

Hi - is there a similar site in which i can share photos and friends can easily save the picture if they like it? of course facebook works, but the quality is really bad when i upload them on there. i know flickr you can do it by going into "view all sizes" then selecting the ones you want, but any other sharing site that makes it even easier for my friends? prefer free sites

Theres Panormaio and Photobucket. i find Flickr the best one though.
