Sorry for the delayed response!
How many images do you have in your images folder and all subfolders? Spine has some limits since system resources are limited. Consider what would happen if you put / as the images path
it would try to scan your entire disk! Spine finds up to 10,000 images, looks up to 16 folders deep, and will watch up to 50 folders.
Spine only shows folders that have images. If you are actually hitting the limits, we could show all folders so you can still get to your files. Before doing this though, I'd like to make sure we know why your images don't appear.
As a workaround, you can drag any image and then rename it to the path you want.
