Wordless has the ability to generate some dummy content (images or text) using some online services.

For this to work you need to be connected to internet, as the dummy content is dinamically generated by online services.

PlaceholderImage abstract class

To use web services a PHP class describing the services is needed in Wordless. In wordless/helpers/placeholder_images there are classes describing the online services available in Wordless to be used to generate dummy content.

The main class is PlaceholderImage, which must be extended from the other classes.

How to add a service to Wordless

Adding another web service is really easy. Create a class in wordless/helpers/placeholder_images which extends PlaceholderImage and reimplement the PlaceholderImage::url() method (follow the documentation for this method to check arguments and return).

For examples look at wordless/helpers/placeholder_images/lorem_pixel.php or wordless/helpers/placeholder_images/placehold.php.
