This extension creates url's for placehold.it images.
NEW UPDATE: Images now open a save dialog box rather than opening the image in a new tab.
This extension uses the popular placehold.it service to generate images with the specifications, such as colour and dimensions, that you specify.
v 1.5 - Changed the extension to automatically download the generated image, rather than opening it in a new tab.
v 1.5.1 - Fixed URL encoded text being used for the save filename.
v 1.5.2 - Tweaked the extension to load faster.
