As Michael pointed out, what you are actuall y doing here is assiging the
value "127.0.0.1" to the associative array element $_SERVER['REMOTE_ADDR'].
You should write:
<?php
if ($_SERVER['REMOTE_ADDR'] == '127.0.0.1') {
echo $level1, '_', $level2, '_', $imageNO, ' ', $display;
}

Note the == instead of = and also note the use of single instead of double
quotes around the string, which stops PHP from parsing the string to
discover if any substitution needs to take place.
