Create image thumbnails from uploaded image files to help downsize large resolution images that need to be displayed on your website in a smaller resolution.

Excellent addition for custom blog sites or any kind of site that allows image files to be uploaded. You can downsize uploaded images as well as keep the original image if you want!

*Original uploaded images can be saved to the file system. *Thumbnails will be saved to the file system automatically.

Example MVC application is located at https://github.com/godfathr/ThumbnailWebExample
