broken image link for representatives

Thank you for this plugin!! The legislative search works great, but when I display photos the senators show up but the representative image is broken.

I have turned images off but can recheck the box for troubleshooting purposes.

The broken link goes to https://nationalparksaction.org/wp/wp-content/plugins/civic-geo/photo/unknown.jpg
