Connecting Photo's in File Maker Pro

[OSXFreak]

I currently set my FMP database to IMPORT the data from an ODBC connection that is linked to an MSSQL server.

This is the SQL server that we use for our ecommerce website.

In that SQL server I have an area called photoitems. This is set up to show a relative link back to a specified location for photo's.

When I imported this in to FM, it shows in the photo box as /picturecategory/123456.jpg

How do I set this up so that this is pulling the actual image from the location on my SQL server and displaying it on my FM design?

I assume I need someway to tell it that the location of the image is //servername/picturecategory/123456.jpg, but for the life of me can not figure out how.

Thanks
