You are using the OR operator, so if any one of the conditions is true, the echo will operate.  Obviously, in this case, it will always be true because of the first and last conditions.

$type!="gif" or ($type=="gif")
is allways true, remove ($type=="gif") or replace it with
($type!="png")

You need an AND condition and don't need the $type=="gif"


$type="gif";
if(($type!="gif")&& ($type!="jpeg") )
{
echo "You can only upload a photo";
}
