Save file pointers to database

Hi,

My application requires saving of images (5 per trial) which is to be used for processing in later stages. I am storing trial data in database using LabVIEW database connectivity toolkit. I would also want to save images with the database for easy data management. But I do not want to save the entire image as it makes my db bulky and slow overtime. I would rather create a file reference/pointer to the image in database. Any ideas on how to create a file reference in database.
