Attach multiple image formats, not just JPG to email

This is what i have so far...

 MemoryStream imgStream = new MemoryStream();
        System.Drawing.Image img = System.Drawing.Image.FromStream(fuImage.PostedFile.InputStream);
        string filename = fuImage.PostedFile.FileName;

        img.Save(imgStream, System.Drawing.Imaging.ImageFormat.Jpeg);
        imgStream.Seek(0L, SeekOrigin.Begin);
        EmailMsg.Attachments.Add(new Attachment(imgStream, filename, System.Net.Mime.MediaTypeNames.Image.Jpeg));

So it attaches a JPEG image fine. But i want to change it so that it allows PNG's and GIFs.

You've probably have found this answer by now, so this answer is for anyone else who runs into this issue. 

    Image image = ConvertToImage(response);
    Stream imageStream = ToStream(image, ImageFormat.Png);
    LinkedResource logo = new LinkedResource(imageStream, "image/png");

Above is a sample worked for me, ConvertToImage returns System.Drawing.Image and ToStream returns System.IO.Stream.

I hope this helps!

try this:

 string ext = System.IO.Path.GetExtension(this.imageUpload.PostedFile.FileName);

 string low = ext.ToLower();

 MemoryStream imgStream = new MemoryStream();

                System.Drawing.Image theImage = System.Drawing.Image.FromStream(imageUpload.PostedFile.InputStream);

                string filename = imageUpload.PostedFile.FileName;

              if (low == ".jpg")
                {
                    theImage.Save(imgStream, System.Drawing.Imaging.ImageFormat.Jpeg);

                }
                else if (low == ".gif")
                {
                    theImage.Save(imgStream, System.Drawing.Imaging.ImageFormat.Gif);
                }
                else if (low == ".tif")
                {
                    theImage.Save(imgStream, System.Drawing.Imaging.ImageFormat.Tiff);
                }

            imgStream.Seek(0L, SeekOrigin.Begin);

                if (low == ".jpg")
                {

                    mMailMessage.Attachments.Add(new Attachment(imgStream, filename, System.Net.Mime.MediaTypeNames.Image.Jpeg));
                }

                else if (low == ".gif")
                {

                    mMailMessage.Attachments.Add(new Attachment(imgStream, filename, System.Net.Mime.MediaTypeNames.Image.Gif));
                }

 else if (low == ".tif")
                {

                    mMailMessage.Attachments.Add(new Attachment(imgStream, filename, System.Net.Mime.MediaTypeNames.Image.Tiff));
                }

doing .png seems a little trickier, but at least that's on the right track.
