Check out Converting image files to OTA file format. The code is in C#.

You need to encode the binary image format to a format (e.g. base64) that can be transferred following the SMS specifications for content streams. The SMS specification imposes some limits on the length of a single message (140 octets) and your picture really has to be smaller. Otherwise, this'll be transported as a series of SMSs which you'll need to pull together on the receiving end.
