I don't agree with some of the posts here. I do not believe we should accept sloppy work just because a national magazine shows a picture. Rather, write the magazine and tell them they should pay attention to the workmanship shown in their illustrations. I did this recently with a book company about the picture on the cover of one of their books. They explained it away with something like "cropping the picture caused the problem"
Well I don't accept that. Write the magazine and tell them we expect better work. It doesn't have to be outstanding but should be good without obvious sloppiness.
