Re: Filesystem vs. Postgres for images

Your code is retrieving the file from the file system. It doesn't have
to be accessible from the web server at all. Our current design uses a
JDBC connection to the database for the metadata (digital
signature,path,name,file type, etc..) and a SOAP call to the same server
(but doesn't have to be) to retrieve/store the image data.
