| This article describes how you can rotate images in PHP. We deal with two examples, firstly rotating by 45 degrees and then by 90, going in to some depth to ensure you understand how the code is working. You might find this useful if you are, for example, building an online photo gallery and you want to rotate your pictures within PHP rather than having to rotate them on your computer. This is a powerful feature to have. |

| Worried about bots? Then create CAPTCHA images to prevent bots from taking advantage of your site. You may be wondering what a CAPTCHA image is. Here's a brief synopsis from Wikipedia: A captcha (an acronym for "completely automated public Turing test to tell computers and humans apart") is a type of challenge-response test used in computing to determine whether or not the user is human. Captchas are used to prevent bots from using various types of computing services. Applications include preventing bots from taking part in online polls, registering for free email accounts (which may then be used to send spam), and, more recently, preventing bot-generated spam by requiring that the (unrecognized) sender pass a captcha test before the email message is delivered. |

| This tutorial focuses on a thumbnail generation script. Rather than generating a smaller representation of the image, it cuts out a section of the photograph to create an obscure snapshot of the photo itself. The thumbnail's size is variable also, so the script be used across different sites to create different sized thumbnails where needed. |
