A simple dummy-image generator in php for local development.
Link to block.php as an image. Following the file, set your parameters:
block.php/{width}/{height}/{bg-color}/{text-color}
Width is mandatory - everything after is optional. If no height is given, you get a square image. If no colors are given, #444 and #BBB are used for the background and text, respectively.
Currently images are returned in png format.
Blatantly copied the idea from Placehold.it - http://placehold.it/
Using Bitstream Vera Sans for the text - http://www-old.gnome.org/fonts/
