PHP Image uploader

Ik was bezig met een PHP script om images te uploaden. Ik had gekozen voor jpg,png,jpeg,gif maar op de een of andere manier werkt alleen .gif.
______________
Dit is de php zelf (zonder html):

if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/jpg")
|| ($_FILES["file"]["type"] == "image/png"))
&& ($_FILES["file"]["size"] < 20000))
{
if ($_FILES["file"]["error"] > 0)
{
echo "Return Code: " . $_FILES["file"]["error"] . "
";
}
else
{
echo "Upload: " . $_FILES["file"]["name"] . "
";
echo "Type: " . $_FILES["file"]["type"] . "
";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb
";
echo "Temp file: " . $_FILES["file"]["tmp_name"] . "
";

if (file_exists("upload/" . $_FILES["file"]["name"]))
{
echo $_FILES["file"]["name"] . " already exists. ";
}
else
{
move_uploaded_file($_FILES["file"]["tmp_name"],
"upload/" . $_FILES["file"]["name"]);
echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
}
}
}
else
{
echo "Invalid file";
}
?>

Hoe kan ik ervoor zorgen dat .jpg/jpeg/png ook werkt?

Bedankt alvast.

|| ($_FILES["file"]["type"] == ".jpg")

Zo denk ik

Heb ik net geprobeerd bij allemaal, Invalid file
Edit: het is toch niet zon uitgebreid script, is er iemand geintereseerd in een upload script te maken voor mij? Je krijgt er natuurlijk punten voor
Meer info per P.B.

kijk gewoon op phphulp of sitemasters.be daar vind je er genoeg
