Images files are files, unless there is compelling reason to store them in the database, the place they belong is the file system, where you get benefits like easy backup and replication, distributed across multiple machines, directly served by the webserver, and all the last-modified-date and etag supported by the webserver to achieve better performance, etc.
if the number of images is expected to grow, and different sizes of one image are expected to be created (e.g. thumbnail images etc.) in the coming release, a plan to migrate images from db to file system is strongly suggested.
