Some pictures, for some uses, yes. Each photo is clearly marked with the license the photographer has elected to put on it. If it has a Creative Commons Attribution license, you may use it as long as you attribute it to the creator; if it says all rights reserved, you need permission; and so on.
The two most widely used sites for online storage and sharing are Picassa and FLickr. Any one of them also gives you the ability do some editing on the pictures. If you would like to show them you could also use facebook
