Neocities.org
Would it be easier to add the neocities generated thumbnail, so each site automatically updates the preview. Might save you a step manually creating a thumbnail and having to host it. Mine is something like: https://neocities.org/site_screenshots/23/71/dann/index.html.540x405.jpg

oooh nice idea!
The two numbers in the middle will be different for everyone, so that prevents easy copy and paste, but you can right-click on their profile and copy the image link in any case. (or one of the updates in their feed)
