:) In the manual you can find examples of loading/reading binary data using MySQL++:
http://www.mysql.com/documentation/mysql++/4_Tutorial.html#SECTION03161000000000000000

You can use LOAD_FILE() function to put images into a database, for example:
INSERT INTO table_name(blob_field) VALUES
(LOAD_FILE('/full/path/to/your/file'));
Read about LOAD_FILE() at:
http://www.mysql.com/doc/S/t/String_functions.html
If you don't use LOAD_FILE() - don't forget to escape chars. You
can find the list of chars to escape and escape sequences at:
http://www.mysql.com/doc/S/t/String_syntax.html
To read binary data use the SELECT statement.
