Graphic?

Consider including a graphic on this page at the top? Something like https://www.creativebloq.com/advice/image-file-formats or https://www.informaticsinc.com/blog/2014/how-choose-right-image-file-format

Might've missed it on the page, but I can't determine if these images are CC-licensed. Will look for CC-licensed options

No, indeed. I didn't want to do the work of finding CC licensed equivalents in case using a graphic was not a welcome suggestion:)

Recommending we don't bother with this suggestion for a graphic since it's not a need to have:)
