Grid doesn't show

Hi there!
Thank you for your advice, tried playing more and I got some improvements but still it doesn’t work correctly. Now I have links listed but without thumbnail pictures.

Check the link: http://krafthouse.rs/Radical_Graphics/new-staff-grid-plugin/ (please don’t mind links from my original post, they don’t work anymore)

Here you can find all the options I selected:

As I said I’m using this for my custom post type, and here I don’t have thumbnails in grid view. But when I change Query Post source to be regular Post I get the thumbnail pictures in grid view. So here both options in “Layout settings” get the picture in thumbnail “Featured Image” and “First images from content”.
So I guess problem is that plugin is not recognizing first image in my custom post type.
I would really like to be able to use option “First images from content” it would make some other staff I want to do possible.

I think it’s important to say that I am using Pods plugin for creating this custom post type, maybe it have to do something whit how Pods are inserting images? (my really hard guess)

Do you have idea what it could be or how could I fix it?

Unfortunately I can’t make new post type without Pods plugin, I don’t know how to do it. 🙂

Anyway I made some other solution without this plugin. Thank you for you time!
