Lock it, lock it real good

Take some control of the image that's displayed. Include a lock query string parameter and give it a value that's a positive integer. While our cache is not updated, and sometimes for longer, the same image will be returned by our server.

<img src="https://loremflickr.com/320/240?lock=1" />
<img src="https://loremflickr.com/320/240?lock=212" />
<img src="https://loremflickr.com/320/240?lock=30976" />

Multiple images on the same page

Your browser might cache the images when you request the same URL multiple times on the same page. You can resolve this by adding a meaningless querystring to the URL. So, for example...

<img src="https://loremflickr.com/320/240?random=1" />
<img src="https://loremflickr.com/320/240?random=2" />
<img src="https://loremflickr.com/320/240?random=3" />

Free!?

Yes, but, running this service does come with occasional headaches and bandwidth peaks. Feel free to chip in for the price of a beer.

JSON is my drug of choice

https://loremflickr.com/json/g/320/240/paris,girl/all

If you're planning to conquer the world and need some JSON to complement your nefarious plan, we've got you covered. Note that the image URL that is returned is cached and might not stay around for too long.
