getimagesize problem!

[RedDragon]

hi im using this code to verify that an image is valid

		if (!ereg("^http://.*\.(bmp|gif|jpg|jpeg)$",$avatar)) {
			message($lang_avatarwrongtype, $lang_plscorrectavatar);
		} else {
			$avatarsize = @getimagesize($avatar);
			if($avatarsize['0'] > $settings['avatarw'] || $avatarsize['1'] > $settings['avatarh']) {
				message($lang_avatartoolarge, $lang_plscorrectavatar);
			} else {
				if($avatarsize['0'] < $settings['avatarwlow'] || $avatarsize['1'] < $settings['avatarhlow']) {
					message($lang_avatartoosmall, $lang_plscorrectavatar);
				} else {
					$db->unbuffered_query("UPDATE ".$prefix."users SET avatar='$avatar' WHERE (username='$membercookie')");
					message($lang_successfullyavatar, $lang_forwardmemcp, "cp.php");
				}
			}
		}

i got the response form some members that it gives out an error when opening the image or even sais its to big/small (the image lies between the restricitons so it should work)

anyone got an idea what could be wrong

thx for your help

anyone?

Try taking the numbers out of quotes:
$avatarsize[0] rather than $avatarsize['0']

You should be using an integer, not a string. See what it does then.
