Uploading photosize ??

[Marc]

I need help on coding a little part into this script where it will error filesizes higher then 100kb.
Meaning of the script is to let people post max 1 picture on my site with a max size from 100 kb or 2 pictures from 50 kb each.
I really don't know on how to get this to work, so any advice or even better "implemented"coding into the script would be very helpfull. Thanks

<?
function upload_file($in, $out, $type)
{
move_uploaded_file($in,$out);
}

	function man_MIME2Ext($mime)
	{
	  switch($mime)
		{
	    case "image/gif" :
						return "gif";

	    case "image/pjpeg" :
						return "jpg";

	    case "image/jpeg" :
						return "jpg";
	  }

		return "";
	}

	$rPhotos = q("SELECT id FROM dt_photos WHERE member_id='$fMember[id]'");

	if($filename_1 != "" || $filename_2 != "")
	{
			$number = 1;

			if($filename_2 != "")
			{
				$number = 2;
			}

			if(man_MIME2Ext($HTTP_POST_FILES["filename_$number"]['type']) != "")
			{
					$file_source = $member_code."_$number.".man_MIME2Ext($HTTP_POST_FILES["filename_$number"]['type']);
					upload_file($HTTP_POST_FILES["filename_$number"]['tmp_name'], "photos/$file_source", man_MIME2Ext($HTTP_POST_FILES["filename_$number"]['type']));

					if(e($rPhotos))
					{
						q("INSERT INTO dt_photos (filename_$number, member_id) VALUES('$file_source', '$fMember[id]')");
					}
					else
					{
						q("UPDATE dt_photos SET filename_$number='$file_source' WHERE member_id='$fMember[id]'");
					}

                    q("UPDATE dt_profile SET status='3' WHERE member_id='$fMember[id]'");
			}
	}

	$fPhoto = f(q("SELECT filename_1, filename_2 FROM dt_photos WHERE member_id='$fMember[id]'"));

	include "templates/upload_photo.ihtml";

?>

You should probably use (from php.net):
filesize ( string filename)
Returns the size of the file in bytes, or FALSE in case of an error.
The results of this function are cached. See clearstatcache() for more details.

Do it somewhere between the upload and db-update, then return false if the size is over 100kb.
