You can take things and put them places to talk about them or point and giggle or whatever.
Just don't hotlink, alter my stuff*, claim you drew it or try to sell it.
(And yes, posting someone elseís art on your MySpace/Facebook/dA/whatever page and never overtly saying that you made it but letting people think you did counts as claiming you drew it, so donít do that.)
Credit or links back aren't all that necessary since I've got the name of my site plastered on every picture, but they would be appreciated nonetheless.
*Making icons or web graphics is okay, as long as you credit. Recolouring is not.
