With permission from the other site, I am supposed to periodically download an image hosted on another site and include it in a collection of webcam photos on our site with an external link to the contributing site.
This hasn't been any issue for any of the other sites, but with this particular one, I can't open the image to resize it and save it to our server. It's not a hotlinking issue because I can create a plain ole' <img src="http://THEIRIMAGE /> on a page on our site and it works fine.
I've tried using $img = new Imagick($sourceFilePath) directly as with all the others, as well as trying to use PHP's copy and also trying to copy the image using cURL but when doing so, the page just times out with no results at all.
Here's the image in question: http://island-alpaca.selfip.com:10202/SnapshotJPEG?Resolution=640x480&Quality=Standard
Like I've said, I'm able to do this sort of thing with several other webcams, but it isn't working with this one, and I am stuck as to why it isn't. Any help would be greatly appreciated.
Thank you.
In order to reduce bandwidth and server load some sites block certain bots from accessing their content. Your cURL request needs to more closely mimic an actual browser, which would include a referrer (usually), user agent, etc. It could also be that there is a redirect and you haven't told cURL to follow redirects.
Try setting more opts like this:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_ENCODING , "gzip");
curl_setopt($ch, CURLOPT_REFERER, $url);
curl_setopt($ch, CURLOPT_USERAGENT, 'PHP');
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_AUTOREFERER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
If that doesn't work, get the user agent from an actual browser and put it in there and see if that makes a difference.
Try using file_get_contents().
for example:
$url = 'http://island-alpaca.selfip.com:10202/SnapshotJPEG?Resolution=640x480&Quality=Standard';
$outputfile = "tmp/image" . date("Y-m-d_H.i.s");
$cmd = "wget -q \"$url\" -O $outputfile";
exec($cmd);
$temp_img = file_get_contents($outputfile);
$img = new Imagick($temp_img);
Can you try this and get back to me?
