Resize Image!!

[Adam J Knight]

Hi all,

I am trying resize an image using the following code.

//resize image
System.Drawing.Image ImageUpload =
System.Drawing.Image.FromFile(String.Concat(Server.MapPath(FilePath),ImageName));

// create the actual thumbnail image
System.Drawing.Image ThumbnailImage =
ImageUpload.GetThumbnailImage(250,ImageUpload.Height * 250 /
ImageUpload.Width, new
System.Drawing.Image.GetThumbnailImageAbort(ThumbnailCallback),
IntPtr.Zero);
ThumbnailImage.Save(ImageName)); //ie: test.jpg

However i keep getting this error:
Exception Details: System.Runtime.InteropServices.ExternalException: A
generic error occurred in GDI+.

Any one have any ideas?
Cheers,
Adam

Take a look at this...

I seem to remember having to process it from memory. If I recall correctly
the GDI+ error only occurred if I tried to process an image from disk that I
had only just saved, which is why I decided to process from memory instead.
