I recently had a client that pulled photos from google images to give me for her website. I tried to explain this was not acceptable. It is not legal and the resolution poor. This article on Manta I found interesting and supports what I always try and tell clients. Here is the link to the entire article and a small portion below.

1. Find the right images

Finding the right kind of image is incredibly important. Great images can add another dimension to an article or page that can encourage people to share the page and create some great backlinks. Research shows that while text is still the first thing seen on the page, the image is what sells the page.
Here are some of the best places to actually find images:

• Flickr – Probably the de facto service for finding free images. They have a really useful creative commons search as well. Skellie has an excellent article on how to find Flickr images.
• stock.xchng – Weird name, but a ton of royalty-free stock images.
• iStockPhoto – Large selection of stock photos that you can buy.

You can also use Google Images to find images for your site, as long as you search with the proper licensing. (They allow you to search Creative Commons and other public licenses.) But you have to be very careful when using images, as if you don’t have the permission to reuse it, companies and sites can take legal action against you.
The general rule of thumb is this: if the image isn’t Creative Common licensed or you didn’t buy or create it, don’t post it.
