I need to use a bunch of stock photos for my blog. I'm really confused with all this and need some discussion here.. 1. Do you use Creative Commons licensed images and credit the owner, etc? And where do you find a big variety of images under CC? 2. Do you just use the images without crediting? What are the chances of getting sued or getting a DMCA? 3. Does placing ads on your blog where the images are count as "commercial use"?
