Provide example for license text for image

[SvonGrebmer]

"You can now download the image and move it to your project folder (maybe call it penguin.jpg). In your manuscript file, find the line that says “add image here”, remove it, and add the image instead, including proper attribution."

Readers might be tempted to just add the image and then peak into the solutions for what to include in the license text - maybe prevented by giving readers an example?
