Exposes global functionality for creating image styles.

Code

function image_style_url($style_name, $path) {
  $uri = image_style_path($style_name, $path);

  // If not using clean URLs, the image derivative callback is only available
  // with the script path. If the file does not exist, use url() to ensure
  // that it is included. Once the file exists it's fine to fall back to the
  // actual file path, this avoids bootstrapping PHP once the files are built.
