How best to handle image attribution and copyright notice?

Hi,

Some images I want to use as featured will need credit name and a link to copyright inf, e.g. creative commons https://creativecommons.org/licenses/by-nc-nd/2.0/

What’s the best way to handle that, are there code snippets I can wrap around this at the top of the post to display this info unobtrusively / nicely beneath the image?

thanks
Saul
