Thumbnails not displaying

[madman411]

Hi Everyone

I have an attachment table where users can upload documents or images. The table is located in my Data file. In my UI file the information is all there and displayed correctly, however the container field itself is only showing a "JPEG" logo with the filename displayed beneath rather than the actual image itself. I am not sure what I'm doing wrong here but I think it may be because the attachment table is being referenced from another file(??). I have checked over all my container and storage settings but I'm still not being shown a preview of the image itself.

If someone can point me in the right direction I'd be very appreciative.
