Tumblr - Randomizing blog post order

Tumblr - Randomizing blog post order

Hello,

I am completely new to coding, html java and etc.
I have recently reated a blog that showcases my photography. However the theme that I have installed and Tumblrs default orders my photo blog posts in chronological order by date.

I am looking to change this to randomizing the appearance of my photo blog posts so that upon every load of the page the user will have a change to view my 100+ amazing photos.

Anyone have a javascript code I can copy and paste into my tumblr html code?

I read online that randomizing elements using javascript is easy but I have not a clue what code to use or how to code. Sadly I am a copy and paste of codes.

Anyone with experience using Tumblr and know javascript?
