doctorbull,
just in case you want to know what exactly you are doing with the values you are entering into the .htacess, you are or should be overriding php.ini settings. this may or may not be allowed by your hosting provider, you need not ask them if they have a quota on the hosting limit, but what is the max_upload setting on the php.ini. the information you have been provided here is accurate and depending on your hosting providers server setup, this may or may not work. since it appears you see more are allowed to use .htaccess then i would venture to say that this addition of values in the .htaccess should most likely work out for you. please post and let us know if you get anywhere?

you can also run a php script on your server and determine what the php.ini settings are for max_upload <? phpinfo (); ?> name this file, call it up in your browser, you can view your php.ini settings if this feature is not blocked from your hosting provider. if you see that the max_upload is limited to 2mb which is default, then you can take two avenues, you can post to your support and request that they increase that value, or you can try the .htaccess values.

later,
