Advertising a product by using the picture of an item that is more beautiful or larger than the product being marketed, while including under the picture a caption that this picture is for illustration purposes only, in essence only for advertisement and not a true representation of the product, could be considered a form of Gneivas Daas, deception. If the purpose is that viewers should think that this picture really represents the product, the mere inclusion of the caption on the bottom will not help in actuality. Sometimes, of course, the purpose of the picture is just in order to enhance an article, and people will not necessarily think that this picture is connected to the article, because its true function is simply to make the article more interesting to read, and is obviously not a problem. However, if the picture’s purpose is to facilitate selling or marketing an item, and its function is to try to convince people that the item is similar to that which is in the picture, this can be a serious issue of Gneivas Daas, deception.
