check if picture on other server exists...

[sid]

ok - i link some webcams from my page - what would be the easiest way to check if the picture files actually exist? of course they are on another server - so i only can do it through the url.

it should be like that:

$pic = "http://www.server.com/cam.jpg";

if (file actually exists ($pic)) {
    print "<img src=$pic>";
}
else {
    print "cam not online";
}

thanks a lot

fopen() returns false if file doesn't exist. Even over http.
