And Google was sued many times back in the day for the same thing, because of their indexing of the web. They won out under fair use for the exact same reasons that all of these lawsuits will fail, the way these images are used falls very clearly within the dead center of fair use, and is probably even less questionable than Google's, since Google really does store and display direct copies of pieces of the content that it organizes.
