The WebImage class has properties that expose the Height and Width of the image in pixels. So this will give you the size of the image.

EDIT

I think this post might help you with that, but it requires you have the image saved to disk.

How to get the file size of a "System.Drawing.Image"

Additionally, you could do something like this, though it'll have some overhead as you'll be putting all of the bytes into memory...

WebImage uploadedImage = WebImage.GetImageFromRequest("somefile");
long sizeInKBytes = uploadedImage.GetBytes().Length / 1024;
