Using images from internet on Marketing Pieces.

[Goodfella3993]

I am putting together some Direct Mail Marketing Pieces (catalogs, postcards, etc...). I would like to you images of Automobiles in them. I have found many great images on the internet. Most seem to be Stock photos from the manufacturer.

What are the legal implications of grabbing an image off the internet and using them for marketing a product?

Dont. istockphotos.com is a good place and its not to expensive if you just need a couple photos. There is other ones out there as well. No need to mess around with possible legal issues imo!
