Image generation websites

I'm looking for a service such as placekitten dot com that also includes the dimensions 开发者_如何学JAVAin the image. For example, a 200x300 kitty image would have "200x300" as 'text' overlaying the picture.

Are there any other services doing this?

http://placehold.it/ shows dimensions on a generated image, but it does not have a (cute) picture behind.
