You could do something like this.
var thumbNail = CreateThumbnail(100, 100, fullPath);
public static Image CreateThumbnail(int maxWidth, int maxHeight, string path)
{
var image = Image.FromFile(path);
var ratioX = (double)maxWidth / image.Width;
var ratioY = (double)maxHeight / image.Height;
var ratio = Math.Min(ratioX, ratioY);
var newWidth = (int)(image.Width * ratio);
var newHeight = (int)(image.Height * ratio);
var newImage = new Bitmap(newWidth, newHeight);
Graphics.FromImage(newImage).DrawImage(image, 0, 0, newWidth, newHeight);
image.Dispose();
return newImage;
}

All System.Drawing objects must be disposed with a
using clause, not with .Dispose, as that does not ensure their disposal. The GC does not see System.Drawing instances.I hope you use a library to do this. There are a lots of code samples, but they're not designed for server side use, whereas ImageResizer is.
At least read this article on what pitfalls to avoid if you decide to go copy & paste route.
