Tell me if you agree with this statement and then explain why or why not. "Images on the internet are 'free game' - if someone posted it, I should be able to use it."

I agree that if an image is posted on the internet, then anyone can use that image. I think this because the person that put the image on the internet put it there because he wants people to see it, relate to it, and maybe use it if they want, but if you use the image you have to site where you got it from. Taking credit for someones  stuff is not aloud on the internet so if you site your work or image then i think that images are free game on the the internet.
