  Hi,

  you first need to upload the image and the use GDI+ to resize it. There are a lot of articles about this: http://www.google.be/#sclient=psy&hl=nl&site=&source=hp&q=asp.net+upload+and+resize&aq=f&aqi=&aql=&oq=&pbx=1&fp=2270f60bc51c5286.

  Grz, Kris.

  There is a free, open-source library to handle all the encoding and resizing issues. It supports uploads as well as MS SQL.

  If you decide to roll your own, make sure you read the following article.

  20 Image Resizing Pitfalls in .NET

  A lot of the rookie mistakes are not obvious, and not documented well.
