I am working a mvc web app. I upload a image to use it as system logo. Now if I select image and upload it, it can be replaced easily until image file is not of large dimesion. For file with large dimension i need to reduce its size to some smaller size to make it look like a system logo. Preferable size for my logo is 100x75. How can I reduce the file dimesion? THanks, kapil

try this. I found it in the msdn, and it works.
Bitmap map = new Bitmap(Image.FromFile("F:\\1.jpg"), new Size(20, 20)); map.Save("F:\\5.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);

You can use the classes that are in the System.Drawing namespace.
See this tutorial for details.

The code snippet will likely bring your server down (or at least cause worker process recycling) on a high-traffic site, since it doesn't take care of releasing all the used GDI+ objects right away.

Use the imageresizing.net library. It's 1 line of code to use, and < 200K added to your assembly. And it avoids the 29+ pitfalls in .NET image resizing.
