Hmmm, maybe copied that too hastily from StackOverflow ...

Rick is right, up to a point. But the documentation is very clear:

Quote:
You must keep the stream open for the lifetime of the Image.

Image.FromStream Method (Stream) (System.Drawing)[^]

C#

using (MemoryStream ms = new MemoryStream(byteArrayIn))
    {
    using (Image im = Image.FromStream(ms))
        {
        return new Bitmap(im);
        }
    }

Is a lot safer.
