[Koha] Taking patron images out of db into a directory

Hi all, We'd like to write a patch to move patron images out of db into a directory in the server. By this change, we'd like to satisfy following. 1. The size of database backup will be decreased, by this way one may store db backups more. 2. Database performance will increase 3. It will be possible to put patron images in different disk in the server 4. Easily put images gathered from other systems like (university system, personnel system, etc) What is your idea? -- Mengü Yazıcıoğlu Devinim Yazılım Eğitim Danışmanlık Reşit Galip Cad.
