[Plugin: Special Recent Posts] broken thumbnail images

My thumbnail images have been broken for the last few weeks. Can’t remember for sure, but it might have started when I somehow automated the thumbnail choice for our site’s “Twitter Digest” plugin. I went back to the plugin options to undo it, but can’t find where / how I did that.

Anyway, other thumbnails are broken: http://aksb.org

Any suggestions…?

Thanks,

Lia
