Possible images
So I just removed a huge Mate1 ad from the article, because in my opinion (although I believe it was added in good faith by User:KRW), it's inappropriate for an article about a general product or service to feature prominently the advertising or image of one single product within the class. Some examples I looked at included:
 Soft Drink where the main picture shows a variety of brands on a supermarket shelf (with a photo of the Diet Pepsi product line much lower down)
 Potato chip where two of the three pictures are of chips without packaging, and the third is a non-current ad
 Fast food where all of the food is shown unwrapped (and only the Big Mac is clearly identifiable), plus a nondescript interior photo and a photo of several adjacent restaurants
 Chocolate bar with an unwrapped chocolate bar shown. 
This brings up a quandry: what do we use for images? My best ideas are to make mockups of a hypothetical dating site front page or ad and use them instead of real images. Suggestions?
