A Preview of Image Manipulation in ColdFusion 8

Hot off the press, is my ColdFusion 8:Articles:A Preview of Image Manipulation in ColdFusion 8. In this article you will will learn how to use ColdFusion 8’s new image tags and functions to create a micro image gallery application that creates thumbnails from uploaded images and watermarks the originals using the new CFImage tag and related functions. Additionally you will also learn how to create and use a CAPTCHA image in the form space to ensure that a human and not a bot is trying to upload images.

You will want to download the demo files with the application to follow along with, and of course you will also need a copy of the ColdFusion 8 Public Beta also available on the Adobe Labs. One last thing about the demo application, it is not a full featured image gallery. Its intended purpose is to showcase some of the new ways to manipulate images in ColdFusion 8. More specifically it does not contain functionality to delete to images once added to the gallery. To delete images you have to manually remove them from the application's images directory and thumbs sub-directory.

That said enjoy the article and demo.
