Random Image Chance

I want to create a template where it has a 50% chance of showing one image (1.png) and a 50% chance of showing another (2.png).

<choose>
<option>
[[File:1.png|thumb|200px|center|Caption 1]]
</option>
<option>
[[File:2.png|thumb|200px|center|Caption 2]]
</option>
</choose>

Each has an equal chance of being chosen. Below is an example.
