Check the HTTP result code, if it's `HTTP/1.1 403 Forbidden` then don't display it. — Mike Christensen, Nov 11 '13 at 23:07
i will try get headers. i have tried file_exist and it doesn't work.. — naf, Nov 11 '13 at 23:08
with getheaders i get this Array ( [0] => HTTP/1.1 200 OK [Date] => Mon, 11 Nov 2013 23:13:17 GMT [Server] => Apache [Last-Modified] => Sat, 10 Mar 2012 17:50:24 GMT [Content-Length] => 3672 [Connection] => close [Content-Type] => image/jpeg ) — naf, Nov 11 '13 at 23:12

file_exists() doesn't work across domains. Server side can be done like:

$url = 'http://images.icecat.biz/img/gallery/16678932_9061.jpg';
$header = get_headers($url, 1);
if(strpos( $header[0],'200') === false){
  // do what ever
}

EDIT: fixed for 200 response. Better use curl though, faster it is

I dont get 404 for forbidden images.. i get HTTP/1.1 200 – naf Nov 11 '13 at 23:14
this wont work as i get HTTP/1.1 200 for non forbidden images as well. – naf Nov 11 '13 at 23:19
I tried the restricted image from your example (Using IE) and I get 403, not 200. – Mike Christensen Nov 11 '13 at 23:20
i am using print_r(get_headers($url, 1)); and i get a response of 200 – naf Nov 11 '13 at 23:23
@naf, this answer is correct. maybe you are using the other correct $url so it responds as 200? – fedmich Nov 11 '13 at 23:26
i am using this code to test it.. – naf Nov 11 '13 at 23:33

If you're happy to handle this on the client side, then you could use javascript to deal with this:

You can use handle the onError event to replace the image or do something else in the event that the image cannot be displayed.

See this answer for an example.
