My website doesnt sell any products, its a free content site or orkut scraps images, but i use adsense in my site,.. so only for that reason.. is my site a commercial one?
Yes, it is a commercial venture. The posters above me do not have a clue what the term means in a legal sense.
In addition to being commercial, if you don't have permission to use the images displayed, it is copyright infringement and a violation of the adsense tos - which subjects your account to being terminated and earnings not paid. I highly doubt Disney is allowing you to use or place your copyright notice on their images.
