Local php.ini not being recognized on upload limit

I am trying to increase the size of the upload limit from the standard 2MB to 24MB. Since I am on a shared server, my host set up a custom/local php.ini file and put it in my public_html. i then moved that to the directory where I installed WordPress. I changed the two fields below to ’24M’ but when I go to the uploader, the limit still says ‘2MB’ is there another setting I am missing?

thanks for the help.

upload_max_filesize
post_max_size
