I Need help to create a random weather table..

Hi, guys! I need help! I was trying to create a table to roll the weather in my campaigns, but  i saw that in the tables I can't put a large image, just icons. So I created some macros to do that. Each Macro containing a specific image of weather, sunny, rainny and others, now I need help to create a macro to roll randomly these macros that I've already created. Is it possible ?

Unless you make it super fine grained with multiple levels it will produce unrealistic weather. I choose an area of the world similar to where my players are, match approximate season and randomly pick a year. Go to a weather page and copy a month. You now have weather which will be actually based on the biggest random table imaginable, but will not have tropical storms leading to blizzards in the summer and droughts during rainy months.
