I'd like to free up space in my IMAP mailbox, so I'd like to detach images from large emails to a network share (mounted as drive, let's call it S:/ (\\servername\sharename\)). If I detach this images to a folder on drive S:\, Thunderbird does not show the image under the message body, only "broken image" sign appears. If I double click on the file name, images are opened, so path is OK. If I detach image to local drive like C:\, things are the same. How can I utilize Thunderbird to load detached images content from network drive? I've using many computers, but drive letter for shared folder is the same for all, so maybe this is a good way to access / preview every attachment from every computer. Please help how to fix this problem.
