When it comes to using pictures, it is important that you make sure you choose the best picture possible to get your point across.

For example: I have a brown Labrador retriever. You would include a picture of a brown Labrador retriever and not a different type of dog.

NO:

When needing to find an image, sometimes it is easy and sometimes it is not. One way to find an image is to do an internet search for it and type in exactly what you are looking for or type in key words. Another way to find an image is to take your own. If you have access to the type of picture you need, it is best that you take the picture on your own and use the most authentic version possible in your situation.
