PHOTO;ENCODING=b;TYPE=jpeg:iVBORw0KGg... all data in one line
PHOTO;ENCODING=b;TYPE=jpeg:/9j/4AAQSk... all data in one line
PHOTO;ENCODING=b;TYPE=png:iVBORw0KGgo... all data in one line
PHOTO;ENCODING=B;TYPE=png: iVBORw0KGgoAA... data broken in 76-byte lines
PHOTO;ENCODING=B;TYPE=JPEG;VALUE=BINARY:iVBORw0KGgoAA... all data in one line
