download image from homepage

This should do it :


<?php


$filename = $_GET['file'];


// required for IE, otherwise Content-disposition is ignored

if(ini_get('zlib.output_compression'))

  ini_set('zlib.output_compression', 'Off');


// addition by Jorg Weske

$file_extension = strtolower(substr(strrchr($filename,"."),1));


if( $filename == "" ) 

{

  echo "<html><title>eLouai's Download Script</title><body>ERROR: download file NOT SPECIFIED. USE force-download.php?file=filepath</body></html>";

  exit;

} elseif ( ! file_exists( $filename ) ) 

{

  echo "<html><title>eLouai's Download Script</title><body>ERROR: File not found. USE force-download.php?file=filepath</body></html>";

  exit;

};

switch( $file_extension )

{

  case "pdf": $ctype="application/pdf"; break;

  case "exe": $ctype="application/octet-stream"; break;

  case "zip": $ctype="application/zip"; break;

  case "doc": $ctype="application/msword"; break;

  case "xls": $ctype="application/vnd.ms-excel"; break;

  case "ppt": $ctype="application/vnd.ms-powerpoint"; break;

  case "gif": $ctype="image/gif"; break;

  case "png": $ctype="image/png"; break;

  case "jpeg":

  case "jpg": $ctype="image/jpg"; break;

  default: $ctype="application/force-download";

}

header("Pragma: public"); // required

header("Expires: 0");

header("Cache-Control: must-revalidate, post-check=0, pre-check=0");

header("Cache-Control: private",false); // required for certain browsers 

header("Content-Type: $ctype");

// change, added quotes to allow spaces in filenames, by Rajkumar Singh

header("Content-Disposition: attachment; filename=\"".basename($filename)."\";" );

header("Content-Transfer-Encoding: binary");

header("Content-Length: ".filesize($filename));

readfile("$filename");

exit();
