Saving an image from the browser

[Nathan Sokalski]

I am using ASP.NET, VB.NET, and GDI+ to dynamically create images for
webpages. When I right-click on the dynamically created image to try to save
it to my hard drive, which I send as ImageFormat.Gif , my browser (Internet
Explorer 6.0) wants me to save it as a *.bmp file. The VB.NET line of code
that I use to send the image to the browser is:

textbitmap.Save (Response.Outpu tStream, ImageFormat.Gif )

Why is my browser forcing me to save an image (supposedly) sent as a gif as
a bmp? Is there some other line of code I need to add in order for IE6 to
recognize it as a *.gif file, or is this just a bug in IE6? (Yes, I know
that I can use the Save() method to save it as a file on my computer, but I
want the browser to treat the dynamically generated images the same as other
images, including the ability to download them in the intended format)

A bug in IE6. Deleting your temp. internetfiles is a know remedy.

Does your HTTP Response header list the data type as GIF?

Re: Saving an image from the browser

Yes, I tried including the following line of code immediately before the
Save() method:

Response.Conten tType="image/gif"

I also have the following attribute in my @Page directive:

ContentType="im age/gif"

But neither on seemed to make any difference.
