What free and public image JSON API can I use for testing JSON request

Question

I'm playing around with AngularJS and would like to use some free API's to get some images. I was looking at Flickr but you need to register a app to make use of it. I'm looking for something I can use right of the bat.

http://www.jsontest.com/ comes close but can't get any images.

Answer 1

• What about the "Standard Image Sizes" List over at http://dummyimage.com/#standards?

Edit in 2023:

• http://schematic-ipsum.herokuapp.com/ has a nice lipsum extension that generates images from http://hhhhold.com/

These ones are down.
