Sending image in XML using C#

• On the sender side, start with your image as a byte[].
• Convert the array to a text representation (a base64 string) using Convert.ToBase64String(array).
• Put that base64 string into the XML.
• On the receiver side, simply decode the base64 back to byte[] using Convert.FromBase64String(string).

For details on each of those operations check this other post.
