I would advise against saving images in the database. This usually gives poor performance since files work better from the file system, data in the database etc.

It will also be harder to scale the database when the number of images grows than to just store them in a file system.

I would store the path to the file in the database, you can store a relative path and then have a constant in the web application to the root directory containing the images.
