Convert Byte() to System.Drawing.Image?

Using VB.Net (VS.Net 2k3)...

I'm at a bit of an impasse I think... Is there any way to convert an array
of Byte() into a System.Drawing.Image object without writing the array to a
file, then reading back into the s.d.i object? Couldn't find anything in
MSDN or by Googling...

Thanks!

dim stream as System.IO.MemoryStream
dim img as image

stream = new System.IO.MemoryStream(bytearray)
img = image.fromstream(stream)

Create a MemoryStream around the byte array and call Image.FromStream.

Create a 'MemoryStream' object, write the byte array to the stream and use
'Image.FromStream' to construct the image. Note that the stream must be
kept open as long as the 'Image' object exists.
