I found the solution myself. The method handling the creation of thumbnail images are in file wp-includes\media.php. Code handling filename are line 213 and line 225. hope this helps to people who have same request as me.
if you set the Max width and Max height for medium pics to a large enough value (i.e. larger than any picture that you would upload), no medium sized thumbnail will be generated. the setting is at Options>Miscellaneous
I have the same problem.
WordPress 2.3.1
PHP 5.2.3
MySQL 4.1.22
