I perfer eggs. However, if you were asking me what hosting site I prefer for posting my LEGO MoCs and various other photos I would have to say flickr and photobucket.
Photobucket has good editing tools and customising options.
Flickr has many groups for LEGO and a strong LEGO fanbase.
I got a virus while trying to upload to MOC pages. So I plan never to use it again. Flickr seems to bog my system down (cookie city or something strange ).
so at the moment I use Brickshelf. (not that its any better, better the devil you know)
Brikshelf is one of the most stupid and un-user-friendly download sites I've ever encountered. It's like trying to wank with sandpaper or screwing J+B's mom, in that it's very unsatisfying, is a right pain in the dick and may lead to combustion.
Photobucket or GTFO. Fluckr is for wanna be posers toss wank stains.
I use Brickshelf it's actually pretty simple to use, but it's VERY limited. You have to size all the photo's before hand & labling has some whack guildlines. There's no sort or comments section, only a visitor's counter. But if all you need it a basic image storage for links I recommend that, but if you want more you should go for the better places.
