The Hecktech.ImageHandler is an ASP.NET HTTPHandler designed to process image files on-the-fly. Gone are the days of pre-generated thumbnails, which can get misplaced, renamed, or not updated when their source images are. With the Hecktech.ImageHandler, you can generate thumbnails on the fly, and MUCH more! The Hecktech.ImageHandler, you can resize, rotate, flip and change the file format of images without having to write code. The Hecktech.ImageHandler supports the following file formats:
• Joint Pictures Expert Group (JPEG)
• Graphics Interchange Format (GIF)
• Tagged Image File Format (TIFF)
• Portable Network Graphics (PNG)
• Windows Bitmap (BMP)
The Hecktech.ImageHandler intercepts HTTP requests for images, processes the image according to the QueryString settings (or any .config settings), and serves the image back to the HTTP response, without ever spooling the data to disk.
Also included are extended versions of the Image, ImageButton and HyperLink WebControls, which include properties that correspond to the capabilities of the Hecktech.ImageHandler, to make development as simple as point & click. These controls render the preview image correctly in the Design View of any compatible .NET Design-Time environment (Visual Studio.NET, ASP.NET Web Matrix, etc).

No disk caching?!?

No disk caching? Image resizing eats CPU, and will bring down a server quickly if more than one image is viewed at a time.
Disk caching is a *must* to perform image resizing in a production environment - otherwise your server will slow to a crawl every time the memory cache is flushed.
Looks like the website is defunct now anyways....
Here's an open source HttpModule that is safe for production use. It doesn't touch image requests unless a resize is explicitly requested.

I am currently reworking my company's purchasing extranet application in which I currently have to manage 4 different version of thousands of product images - including high resolution TIFF images for print advertisements. This product is perfect for this application. I just need one hi-res TIFF image version and the rest are created on-the-fly by the image handler...voila! This product has saved hundreds of hours of conversioning and gigabytes of disk space. The thing that I was most impressed with how fast it works, even with large image files. To top it all off the product installs easily, and the web control was easy to work with. All in all one of the best add-on component purchases I have made!
Pretty slick, almost everything I've been searching for!

I've been looking for this kind of image manipulation functionality for quite a while and this fits the bill nicely. Easy to use, fast, and loaded with features. Though it would also be nice to have the ability to save the image files to disk.
