Since we don't know what type of photo's/images the OP is getting from the interent. It is totally possible that she has a legit reason to use them. Not saying that this is what the OP is doing, but we can't jump to conclusions either!!

Case in Point 1: Maybe she is getting them from a royalty free photography site which states that the terms are unlimited. Or even a paid photography site and she is 1) right clicking and copying them the wrong way from the site 2) or using the Save Target As on the wrong image and not on the full size image. YWIM
Case in Point 2: I had a customer who had a legal right to use John Deere, ASV, EZGO golf carts and many, many other types of equipment logo's on his web site, since he sells that type of stuff and has a dealership of their products. I often used logo's found on the internet to place on his equipment sales pages. Would be very hard to catch customers attention with just a big word JOHN DEERE or something like that. I could have made my own JD Logo and it would be great, but it wouldn't be the standard JD logo either.
