thomas and friends mini series

It doesn't seem like weebly would work but there's nothing lost in trying! The checklist qua checklist doesn't need pictures: they're certainly nice to have and useful to plenty of people, but if the goal is just to have a way to keep track of what's in your collection, it's not necessary. The javascript file can be embedded into the html so you could get away with just one single file that needs to be hosted somewhere (I'd help create that file if someone wants to try).

On the other hand if all you want is a list of all the engines (without the saved-checklist functionality): a wiki would be perfect for that! Someone just needs to take the initiative to lay everything out in a useful format (all the information already exists in various wikis, just rarely on one, useful, page -- which was part of the reason I created my site in the first place!).
