This project consists of two variants: www.l-h-o-o-q.org and www.i-m-too-sad-to-tell-you.org. Both use a Google CSE (Custom Search Engine) to obtain images. Images are cached and a simple 50-50 chance is defined for either loading a new image from Google or returning an existing one. This is done to reduce the amount of requests to the Google CSE for which we have to pay.
Indeed, the API-key is missing. It's supposed to be in a file called k.php. Get one via the Google developer console.
