ETA: I also could not care less if someone chooses to rename the file or not. The only impact that has is on SEO and even there it is minimal.
Putting aside a situation where a media kit is provided I have seen travel bloggers use "borrowed" images and/or screen shots on a daily basis.
I believe there was a publicized case of a popular media/entertainment blogger who would use images without permission. The blogger's defense was that since they had scribbled "funny" images on the photos they satire and covered under fair use.
