[Plugin: Content Randomizer] Adding arguments to shortcode

Basically, I’m looking to have a random picture generated on the left side of the page and a random quotation generated on the right (I’m using Divi theme). The content randomizer allows me to assign categories to everything – e.g. images vs text.

[elm_random] is the code that I use to display items from the randomizer.

And the documentation reads: Display randomizer posts. Arguments: Type – text/image/video, Category – all or a specific category. Arguments are not required. Default type – text, category – all.

Any idea how to use these category arguments so I can do what I explain above?

Thanks!
