Don't assume people you steal from, I mean INFRINGE upon, will be excited about being promoted. I'm a photographer and you can ask others that took my work without permission about their web sites being shut down, legal fees, yada yada.
What some of you don't realize are some images earn huge licensing fees and those images showing up all over the place cause dilution of the images worth, so expect some photographers to defend their money makers to the fullest extent of the law.
Depending on who you steal from, I mean INFRINGE upon, especially people that formally register their copyright, you can find yourself facing statutory damages up to $150K and paying $2k or more per image.
If you don't think this happens, read about what PicScout does. They have a service that scans the web looking for anything registered with their service by photographers and photo agencies and when they find something being used without a license a lawyer sends a nice collection letter for a lot of money.
Sounds fun doesn't it?
However, there are many images on Flickr freely available under various creative commons license that you can download for free, with or without attribution.
Look here for more information about free Flickr images:http://www.flickr.com/creativecommons/
One word of caution is that you make the leap of faith that the person uploading the image to Flickr actually owned the image. If they uploaded something to Flickr that didn't belong to them in the first place the creative commons license is meaningless and you'll get sued anyway.
