[Fm-lisp] Exif_Get and calculated container fields

Hi

When the images are inserted into a database via a conventional container field, the Exif_Get plugin works just fine. However it doesn't appear to work when the container field is a calculated field, accessing images that are resident outside of the database. Is this possible in some way, or a limitation of the plugin?

My apologies if this topic has been discussed here before, but the archive link from the webpage is not working

Thanks in advance
