From time to time when answering I so badly want to link in an image of a product to illustrate what kind of product I'm talking about. However I agree that we should not do product recommendations, neither directly (through links to online stores) or by referencing product names/sites/...
In addition you have the licensing issue of just pulling some random image of the net, and including it in your answer.
So my question is: What do you do when you want to illustrate your answer with some product, without endorsing that product, or illustration?
On a sidenote: How do we handle images which are clearly lifted from a random website, without clear licensing?
Currently my attempt at doing this somewhat correctly, is to include links to google searches. Here is an example link looking for illustrative images:
However this is an external link, and the answer doesn't have the catchy image to illustrate my intended solution. Do you have any suggestions on how to get illustrative images legally?
