Creating thumbnails dynamically using ASP
This page shows 4 photographs in JPG format. The views shown below have been dynamically resized using csImageFile. Clicking on each image will link to the full size JPEG image.
This technique of displaying smaller versions of images gives the developer a great deal of flexibility, especially when working with a large picture collection. It is not necessary to produce an individual thumbnail for each image in advance.
This page is simple and contains no important scripting. Each <img> tag points to another script which calls csImageFile, resizes the JPG and streams it using BinaryWrite. The name of each image is passed in the URL, as shown below.
Example:
<img src="showthumb.asp?JpegName=scarborough1">

For interest the photographs are all taken in Scarborough, North Yorkshire. They are our own photographs so you can copy them if you like.
