Scraping photos is a lot different than scraping data, I fully agree. But for the pictures, I am using Flickr's API, and it's not illegal. I have read the terms carefully, and since the site it not a commercial one, I am well within the public API terms. I also link to and credit the source on every photo, as I know each individual has the rights to their own photos.
