Resizing images automatically in code

[glyn6]

I'm after some way of automatically resizing an uploaded image in asp.net so I get a thumbnail and the original. I've tried a few ways which all had awful results and the general answer seems to be "use PHP code to do it as it does it well" which isn't much help

It depends on how you you are doing the resizing, but sometimes rotating the image twice means that you end up with a better quality image. Have a read through this article to see what I mean and whether it applies to how you are creating your thumbnails:

what have you tried so far that has failed?
the first thing I would try is Image.GetThumbnail(...).

you may also get more help posting in your language of choice. resizing images is independent of the asp.net or webforms. it's just part of the .net framework. whether you are using vb, c# or another language; asking in those forums may provide better results.

GetThumbnail can provide relatively poor quality thumbnails if a thumbnail is not already embedded in the image (which is presumably part of the reason for the original post)
