Snap.com offers a free tool that creates thumbnail previews of links on your site. The user hovers over a link and a small preview of the site appears (with a small link to snap.com, of course).
I love that it’s free and very easy to install, but for my purposes there are a few drawbacks:
- can’t enable it for one link and disable it for another one
- no previews of PDFs or images within the same site
Still, it has great potential to make a site more usable (and beats learning how to code a preview-on-hover yourself).
