[Plugin: Dynamic Content Gallery] Showing random posts from a category

Hello everyone,

I use this plugin for my blog and I love the way it looks and works.

But the only small feature that I would like to add to the existing installation of this plugin is, I want x number of random posts displayed from a category, instead of displaying only the recently posted articles, such that every time my blog readers open the homepage, they view some different posts (from a particular category) instead of the same posts again and again.

I believe a minor edit would make it work the way I want, shall appreciate if someone can let me know the exact codes to be placed in the plugin.

Thanks in anticipation.
Deepak
