The picture should be a bitmap picture without alpha channel or mask.
Use the JPEGExporterMBS class for more options.

The returned string has the encoding set to binary (no encoding). If you want to concat the string with another you should change the encoding, so both strings have the same encoding. If you don't handle that RB may convert the JPEG data to UTF8 (Unicode) which will destroy it.

The picture is always encoded with 72 dpi. If you want to set a different dpi value, please use the JPEGExporterMBS class.
