Product Images Thumbnail

I have a product details page and would like to show the product image along several thumbnail pictures of the product, how can I do thi开发者_开发知识库s in asp.net?

.NET has a built-in mechanism for generating image thumbnails:

Create a generic handler that will receive an unique identifier for the image (to load the image, from a database, filesystem or from the web), resize it within the generic handler with appropriate code (see jonfen's answer, but I've never tried it; or hit google with "c# resize image") and return the resized image
