Masking the source of images?

[virtuexru]

How would I mask where my images are being downloaded from (like the images on www.domain1.com are hosted on www.domain2.com, but I do not want people knowing that the images are coming from www.domain1.com).

is there a particular reason you cannot store these images locally ?

We have a data feed from another website that we pay for. Images are a part of this feed (they feed us their updates links into a MySQL database). I don't want people seeing where the images are being fed from though, that is the problem.

Take the link from the feed, save the image locally.. then it appears as if it's from you.  ???

That's not the method I asked for, thanks though. Anyone else have any ideas? Maybe its possible not through PHP but through Javascript?

Hi

 

Never tried it from a remote site, but read the image from the other location into php and then write out from php complete with headers.

 

header("Content-Type: image/gif");
readfile("http://www.domain2.com");

 

Might work (think it depends on a setting in the php ini file to allow remote reads like this, maybe allow_url_fopen ).

If a server's going to remotely request it more than once, it might as well just save it.  You're wasting bandwidth otherwise.

I would agree that is best practice, and to cache it locally. But I presume he doesn't want a link to a real local copy either.

How would I go about saving a local copy automatically?

Hi

 

Something like this (not tested as hacked from a script I have, so may be a typo or 2):-

 

$CacheFileName = '/SomeCacheLocation/SomeImage.jpg';
$RemoteFileAddress = 'http://www.remotesite.com/SomeImage.jpg';
$RemoteFileName = 'SomeImage.jpg';
if (file_exists( $CacheFileName ))
{
header('Content-Type: image/jpg');
readfile($CacheFileName );
} 
else 
{
$img = imagecreatefromstring(file_get_contents( $RemoteFileAddress ));
if ($img !== false) 
{
	$thumb = imagecreatetruecolor($width, $height);
	if ($thumb !== false) 
	{
		imagecopyresampled($thumb, $img, 0, 0, 0, 0, $width, $height);
		imagejpeg($thumb, $CacheFileName, 100);
		header("Content-disposition: attachment; filename=\"$RemoteFileName\"");
		header('Content-Type: image/jpg');
		readfile($CacheFileName );
		imagedestroy($img);
		imagedestroy($thumb);
	}
}
}

 

Basically, check if the image is cached. If so just output that. If not then create an image in memory from the remote location, create another local image and specify the width and height you want (so you can create a smaller / larger copy), copy the first image to the resized local copy, write it out as a jpeg, then put out the headers and do a readfile to read the cached image and output it.

 

All the best
