 /**
 * Helper for generating urls and/or image tags for use with tinysrc.net
 *
 * tinysrc.net provides an API for generating scaled, browser device-specific
 * images. In essence, you pass the API the URL to an image on your own server,
 * and tinysrc.net then provides the appropriate image based on the device that
 * accesses it.
 *
 * Additionally, tinysrc.net allows you to specify additional configuration via
 * the API:
 *
 * - image size. You may define this as:
 *   - explicit size
 *   - subtractive size (size of screen minus specified number of pixels)
 *   - percentage size (percentage of screen size))
 * - image format. This will convert the image to the given format; allowed
 *   values are "png" or "jpeg". By default, gif images are converted to png.
 *
 * This helper allows you to specify all configuration options, as well as:
 *
 * - whether or not to generate the full image tag (or just the URL)
 * - base url to images (which should include the protocol, server, and
 *   optionally port and base path)
 *
