The thumbnails on the WeirsCAM pages work for me. They link to:

The link in the Lake Links directory was outdated and I just fixed it. Is that where you saw the problem?
I appreciate getting reports of broken links in Lake Links since they do change and I can't always keep up with the changes. If you click on the name there is a "Report to Moderator" button to use when you spot a dead link.
By the way, the thumbnail images on the Lake Links listings are provided by Thumbshots, a 3rd party service. Sometimes they aren't working, like right now, but there's not much I can do except complain or wait a while for them to fix the problem.
