We have an excellent guide to the best places to find free stock photos.I have the same problem and here is my solution (after tracing gallery source code) to get album name and the first image in it (can use as thumbnail for this album): Google Images offers help in finding pictures with a Creative Commons license. When in doubt, dig further to determine if attribution is enough or if you need to pay a licensing fee. If you see a watermark, that's a good indication that the owner of that image wants compensation for their work. Not every image you find on Google is copyrighted. Google and other popular websites quickly remove posts that violate copyright laws, and repeated offenses can get you banned. You may have heard of the Digital Millennium Copyright Act (DMCA) takedown notices.

You could get into legal trouble if you download and reuse a copyrighted image without permission. There are ways to limit your search to images that are okay to reuse and reduce the likelihood of seeing explicit photos during a search. Google Images can pull pictures from any website it indexes with few restrictions on the source or content. One critical detail when downloading images is to avoid copyright issues.
