Image in grid "broken", ok in popup window

I’m dealing with a project I prepared in SC 9.0.043 - a form application has a detail grid that displays an image in each row, derived from type “Image (file name)” field. The field definition is set to allow the image to open in another window (pop up)

In the grid the image does not appear and is replaced by broken image icon. Clicking on the icon opens the popup and displays the correct image.

I assume that in the code generation both the field in the grid and the popup are using the same path/filname, but I could be wrong. I often am.

Anyone have any tips how to troubleshoot this, because I have just about exhausted every other avenue.

Thanks

Sort of my bad…

It turned out to be a permission issue (linux server). The image files were copied from a Windows PC to the Linux server.

After screwing around with the permissions I have it working.

But why would it previously NOT display images in the grid, yet in the pop up window?
