IS photos with sites name on it is legal??

If the site name is written on the photo then its under copyrights of that site and its illegal to use them without their permission but you can use it if you give credit to that site.But taking permission is always good.It also depends what sort of site it is.Is it a image selling site or something cause in that case they can charge you and probably would.i guess i read in some FAQ of mylot you cannot use copyrights photos.But you can remove the logo using some software like photoshop it also depends where the logo is if its somewhr in the below or top just crop the photo and put it up until its a logo of site or some kind of main photo or something.

i don't believe so - i think its just to make sure the right people get credit for it.
