Adding an image file extension will render the image in the proper format. Image format is optional and the default is a gif. jpg and jpeg are the same. The image extension can go at the end of any option in the url
Custom text can be entered using a query string at the very end of the url. This is optional, default is the image dimensions (300×250). A-z (upper and lowercase), numbers, and most symbols will work just fine.
Note: Spaces become +
