There is, at least to my understanding of the law, no requirement to credit a photo taken from a media kit. I can think of plenty of reasons it is a good idea and when I bother to remember I do so, but that's usually low on my list of things I'm worried about when producing content.
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.
