2. Add the line below to jreviews_overrides/filter_functions.php, if you are not using filters yet, read the documentation on Getting Started with JReviews developer filters

require_once "bitpixels_image.php";

3. Adjust the fieldname jr_homepage used for the $homepage variable based on the name of the field you used for the website URL.
4. Change the code parameter in the image URL to your own code.
