Solution 1

Try this way.

C#

WebRequest picrequest = WebRequest.Create( captchaUrl );
using( WebResponse response = picrequest.GetResponse() ) {
    using( Stream responseStream = response.GetResponseStream() ) {
        Image myImage = Image.FromStream(responseStream);


    }
}

Edit

And then you can save myImage using Image.Save Method in the image format you want.

But I added important advice to it in Solution 2, with reference to my code, please see.

In addition to Solution 1: strictly speaking, to save something to a file, you don't need to know that it is the image or something else. You can just transparently save the response stream we it is. For an example, please see my HTTP downloader (which, by they way, can continue downloading partially downloaded file after it was interrupted): how to download a file from internet[^].
