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?

Hi,

this was indeed a limitation. But I made a new version (for Mac) today: 
0.3.0. It has the ability to extract Exif data also from container 
fields with images stored as reference.

External jpg files are also accessible.

Win version, improved example file and documentation are following soon.

The link is: 
http://jensteich.de/wp-content/exif-plugin/ExifPlugIn-0.3.0.Mac.zip.

There are two new functions:

Get_Exif_Reference( jpeg_reference ; tag )

which wants a FileMaker container field with jpg images stored as 
reference as first parameter and the exif tag as second.


Get_Exif_from_File( unix_path ; tag )

this function expects a unix path as first parameter: 
'/Users/me/Desktop/myfunnypic.jpg'
