Regex to get vCard base64 string (C#)

Question

I'm having some trouble creating a regex to obtain the base64 string, image type, and encoding of a vcard image. What would be the best way to obtain this, given the example input below.

The below example works for the note property, however it only obtains the image string if there is something on the same line. How can this be modified to include the entire base64 string for the image property?

public void ParseLines(string s)
{
    RegexOptions options = RegexOptions.IgnoreCase | RegexOptions.Multiline | RegexOptions.IgnorePatternWhitespace;

    Regex regex;
    Match m;
    MatchCollection mc;


    ///Note
    regex = new Regex(@"((?<strElement>(NOTE)) (;*(?<strAttr>(ENCODING=QUOTED-PRINTABLE)))*  ([^:]*)*  (:(?<strValue> (([^\n\r]*=[\n\r]+)*[^\n\r]*[^=][\n\r]*) )))", options);
    m = regex.Match(s);
    if (m.Success)
    {
        Note = m.Groups["strValue"].Value;
        //Remove connections and escape strings. The order is significant.
        Note = Note.Replace("=" + Environment.NewLine, "");
        Note = Note.Replace("=0D=0A" , Environment.NewLine);
        Note = Note.Replace("=3D", "=");
    }

    ///Image (NOT WORKING YET)
    regex = new Regex(@"(\n(?<strElement>(X-MS-CARDPICTURE)) (;*(?<strType>(TYPE=JPEG|TYPE=PNG)))*  (;(?<strAttr>(ENCODING=BASE64)))* (;[^:]*)*  (:(?<strValue>\r\n)))", options);
    mc = regex.Matches(s);
    if (mc.Count > 0)
    {
        for (int i = 0; i < mc.Count; i++)
        {
            m = mc[i];
            CP.encoding = m.Groups["strAttr"].Value; //WORKS
            CP.image = m.Groups["strValue"].Value;  //WORKS
            CP.type = m.Groups["strType"].Value;  // ONLY GETS THINGS ON THE SAME LINE


        }
    }


}
