Upload billede PHP

Dette er den kode jeg har til at uploade billede til min mysql database. Jeg får dog hele tiden fejlmeddelelsen at det er forkert filtype selvom det er png eller jpeg ?

$go=0;

if($_FILES["image"]["name"]) {

$size = $_FILES["image"]["size"] / 1024;

if($size > 0 && $size < 1023) {

$fra = $_FILES["image"]["tmp_name"];

$fra2 = $_FILES["image"]["name"];

$tilp = $_FILES["image"]["type"];

$tiltype = strstr($_FILES["image"]["type"],"/");

$tiltype = substr($tiltype,1);

if ($tiltype == "bmp" || $tiltype == "gif" || $tiltype == "pjpeg" || $tiltype == "x-png") {

$tiltype = str_replace("x-png","png",$tiltype);

$tiltype = str_replace("pjpeg","jpg",$tiltype);

$til = "billeder/".time().rand(0000,9979)."-".$fra2;

if(function_exists("move_uploaded_file")) {

move_uploaded_file($fra, $til);

$img = "$til";

$go=1;

} else {

copy($fra, $til);

$img = "$til";

$go=1;

}

}else {$error='<font color=red>Forkert fil-format</font>';}

}else {$error='<font color=red>Fil over 1 MB</font>';}

}else {$error='<font color=red>Ingen fil fundet</font>';}
