nRelate thumbnail errors

Hi guys,

I just installed nrelate on my website http://radshot.com, waited overnight for it to index, got the green light that it’s good to go.

However some related thumbnails are not displaying correctly – they are showing half loaded/gray.

e.g. http://radshot.com/snowboard-photos/powder-turns/kazuhiro-kokubo-straight-line-mt-cook-new-zealand/

Tried re-indexing, still getting the error.

Any help much appreciated!
