Is there an official way to include an image from the internet in a paper?
This is a really good example of why it's important to be careful about copyright from the beginning: there's really no good way to ensure that you can actually secure permissions to use a random image.  In terms of scientific ethics, you can credit the source, but that is completely unrelated to the fact that you may have no legal right to use the image.

As I see it, there are three good paths to proceed:


Track down the source of the original image (e.g., via reverse image search) and see if it happens to come from somewhere that you can acquire a copyright from.
Search for a similar image that is less restricted by copyright (Wikipedia is often a good source of such, due to their restrictions).
Make your own image.  Since you're dealing with a popular piece of consumer electronics, you might even just lay hands on one and take a picture yourself, then enhance and crop as necessary with image editing tools (there's lots of good free tools out there).
