Convert from Image to Bitmap

With two controls a PictureBox and another "PictureBox like" , Pic2, a
control from a dll, I'm stuck on cannot implicity convert
System.Drawing. Image to System.Drawing. Bitmap error.

How do I convert the following code so that the Pic2 can accept the Image
from the stream where it wants Picture property not and Image property.
Here is a snippet, I'm trying to avoid writing to disk.:

Image i = Pic1.Image;

MemoryStream ms = new MemoryStream();

i.Save(ms, ImageFormat.Jpe g); // need to save in jpeg for Pic2

//Read from MemoryStream into Byte array.

Byte[] bytBLOBData = new Byte[ms.Length];

ms.Position = 0;

ms.Read(bytBLOB Data, 0, Convert.ToInt32 (ms.Length));

Pic2.Picture = Image.FromStrea m(ms); // this is the line throwing the
"cannot convert System.Drawing. Image to System.Drawing. Bitmap
Thanks any help would be appreciated,

Hi Fritz,

Introduce an intermediate variable like thi:
ms.Read(bytBLOB Data, 0, Convert.ToInt32 (ms.Length));
Image img = Image.FromStrea m(ms);
Pic2.Picture = img;

And inspect the actual type of this "img" variable.
By the way, why is your assigment of one PictureBox's Image to another's is
so complicated?

The Image class allows loading a bitmap from a graphic file. So far I've gotten it to work with JPG and BMP files. What other graphic file formats are supported in this way? Is this fixed based on the .NET Framework used (e.g., the Image class defines which formats can be used), or can different file formats be added after-the-fact (end-user capability in contrast to developer implementation)? Also, is it possible to save an image in...
