Set Image Control to Bitmap

Hello All, want to be able to pull images from the database and load them
into a bitmap through a stream which I have working. I then want to take
the bitmap and load it into a Image control without haveing to save the
bitmap as a file. Is this possible? Currently, I just display the bitmap
by calling Bitmap.save however, if users do not know to click the image they
can not see the full size. If I can create a bitmap from the stream I know
the size so I can set the properties of a image control and then display the
bitmap in the image. Does this make since or am I going about this the
wrong way? So in a nutshell, I am pulling images from a DB and want to
display the full size without having to actuall save the image to a file.
Any pointers?

TIAYou can make an mypage.aspx page that returns bitmap (not HTML)
1. You need to set ContentType = "img/gif"; or (jpg)
2. You need to set ContentLength to the size of the image
3. Use Response.BinaryWrite to output the image. Or since Response is a
Stream you can do Bitmap.Save(Response);

in your HTML you write <img src="http://pics.10026.com/?src=mypage.aspx">

PS: It's more efficient to use handler for that task. mypage.ashx. But aspx
will work too if you fill more comfortable with aspx.

Here is a way to do this without relying on an external handler such as
another page:

Your page can have an Image control on it, and that Image control can point
to another page (or handler) that retrieves the image.
Here are the details:
