How you can store and retrieve the profile pic picture of the customers around the server ? Within the database or using File System? I heard that storing in DB is more suitable for small images. If size could be small around from 60*60 px to 80*80 px then retreivals could be faster as in comparison to file for system!?

[My database is Cassandra.]

You are able to store an image in Cassandra in raw bytes. if you work with Java, you are able to refer the next link - https://github.com/rantav/hector/tree/master/core/src/main/java/me/prettyprint/cassandra/io

Even the following discussions may help - http://cassandra-user-incubator-apache-org.3065146.n2.nabble.com/Storing-photos-images-docs-etc-td6078278.html
