Hi, asad,

Here's 3 links to online code for generating thumbnails.

You might also want to download and examine the free
Community Starter Kit. It has a thumbnail-generation module :

You can resize the image using the GetThumbnailImage method.
Here's more info:

Or maybe you'll find these custom functions useful that I wrote:

public Image DisplaySize(Bitmap bmp)
{
Response.Write(bmp.Width.ToString());
Response.Write(bmp.Height.ToString());
}

//shrink the image proportionately so that neither height nor width is more
than [NewSize] pixels

public System.Drawing.Image ShrinkImage(System.Drawing.Bitmap bmp, int
NewSize)

{

double NewWidth;

double NewHeight;

double ShrinkPercent;

System.Drawing.Image.GetThumbnailImageAbort myCallback =

new System.Drawing.Image.GetThumbnailImageAbort(ThumbnailCallback);

if (bmp.Width>bmp.Height)

{

NewWidth=NewSize;

ShrinkPercent=(NewWidth/bmp.Width)*100;

NewHeight=(ShrinkPercent/100)*bmp.Height;

}

else

{

NewHeight=NewSize;

ShrinkPercent=(NewHeight/bmp.Height)*100;

NewWidth=(ShrinkPercent/100)*bmp.Width;

}

System.Drawing.Image myShrunkenImage =
bmp.GetThumbnailImage((int)NewWidth,(int)NewHeight,myCallback,IntPtr.Zero);

return myShrunkenImage;

}

public bool ThumbnailCallback(){return false;}
