Make pugbomb cache images

[mhijazi1]

Pugbomb should cache images and thus avoid making a call reddit api each time it is called

Yea I agree, it's a feature on the back burner right now. I'm wondering if I should use redis, since it's a caching tool, or if I should take the opportunity to learn how to use mysql so I can start working on the analytics feature. Thoughts?

This feature can be easily done with an array. There is no need for the overhead of a DB at this point.
