Headers to send image-name?

[nightowl]

Hi,

I've built a website where photographers can sign in and create a free album to show their pictures. It's rather important that the pictures which I show dynamically can also be saved easily. However, even though I think I'm sending the correct headers, when I click "save picture as...", it always shows as .bmp ... (though it is perfectly visisble in IE6).

I'm sending

  $disposition = "inline"; // "inline" to view file in browser or "attachment" to download to hard disk
  $mime = "image/jpeg"; // or whatever the mime type is
  $name = "$picture->filename"; // file name


  header("Cache-Control: no-cache, must-revalidate");
  header("Pragma: no-cache");
  header("Content-Type: $mime");
  header("Content-Disposition:$disposition; filename=\"".trim(htmlentities($name))."\"");
  header("Content-Description: ".trim(htmlentities($name)));
  header("Content-Length: ".(string)(filesize($path)));
  header("Connection: close");

have a look at www.pictureparking.com and see that it actually doesn't work like it should. Any ideas ? What am I missing ?

My IE lets me download all your pictures as JPG automatically. It also works with Firefox.

However, here are some tips that will probably fix your problem.

1. Add "\n" to all your header calls.
2. Remove htmlentities().
3. Add a space between "Content-Disposition:" and $disposition (I don't know if this one really matters)

header("Cache-Control: no-cache, must-revalidate\n");
header("Pragma: no-cache\n");
header("Content-Type: ".$mime."\n");
header("Content-Disposition: $disposition; filename=\"".trim($name)."\"\n");
header("Content-Description: ".trim($name)."\n");
header("Content-Length: ".(string)(filesize($path))."\n");
header("Connection: close\n");

Also, I don't think you should have the "Cache-control" headers for the image. I believe you use those for web page headers. Try taking those two lines out and use them in the start of every page. I have no idea what the "Connection: close" is supposed to do, but see if removing that helps.

I don't know for sure if any of the above suggestions will help, but keep playing around until you have what you want. And if nothing works, I apologize for wasting your time. 😃
