I building a user system and decided to use the Gravatar (I know, I know) system for user icons.
Since Im already accessing the database to grab user data, I was wondering if it made sense to store the users's gravatar URL in the database so I didn't have to take their email address and MD5 it every time it is used.
In PHP 5.2.X - And I assume that MD5 is pretty quick. But wouldn't it be quicker not to do it an just grab it from the DB?
