placeholder images for prototyping

placehold.it is a great little service which makes you think why didn't I think of that before. I found it via Twitter Bootstrap, bascially it allows you to quickly drop in some placeholder images by specifying a few attributes such as the image on the left which was created with <img src="http://placehold.it/150x150&text=Hello world" />. There is more to the service such as serving up specific file types and changing the colour of the box etc.

Of course you can roll your own version with CFML, check out Andrew Mercers blog post if you are interested: webonix.net/post/cfml-image-place-holder-custom-tag.
