Broken Thumbnails in Gallery TV?

I have a MIGX image gallery on my site, and when I select images, everything seems to be working, but the image thumbnails are broken (see screenshot: http://www.screencast.com/t/EpsAcAx5hBt ).

Relatedly, if I click to "Edit" any image, the image value always resets -- the dropdown doesn't stick.

Is this due to a bad configuration on my part (e.g. in the Media Source)? Or is it because my server doesn't have the imagick.so installed?

Thanks for any pointers! [ed. note: Everettg_99 last edited this post 11 years, 2 months ago.]

has the sourcecode of the image in your grid the correct source?
I think there was a bug, where MIGX didn't get the correct mediasource in the grid in some situations.

This should be fixed on the github-files.
I'm hoping, I can upload a new release to the repo soon.
