    If you're on an apache server this is really simple.

    1. Create a file called .htaccess in the directory in which your files exist. For me it was assets/.htaccess.
    2. Add the following to the file AddType application/octet-stream .jpg. You can add a new line for each file extension that you need. E.g. AddType application/octet-stream .pdf
    3. Save your file
    4. Clear your browser cache
    5. Refresh your browser and enjoy!

    Browsers recognize jpg URL's and hand them over just like a .htm, so I don't think you can force it on the user-end (not positive on that, though).

    Try to change this:

    header("Content-disposition: attachment; filename= ".$file."");

    To:

    header("Content-disposition: attachment; filename= ".$file);

    If the above doesn't work to you, here a function to force a file to be downloadable:

        <?php
function downloadFile($file, $type)
{
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Disposition: attachment; filename=$file");
header("Content-Type: Content-type: $type");
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize($file));
readfile($file);
}

    downloadFile("sd.jpg", "image/jpg");
    ?>

    This worked for me 

    header("Pragma: public");
header('Content-disposition: attachment; filename='.$title);
header("Content-type: ".mime_content_type($sample_file));
header('Content-Transfer-Encoding: binary');
ob_clean(); 
flush(); 
readfile($sample_file);

    I also added the following to .htaccess

    SetEnvIf Request_URI "\.jpg$" requested_jpg=jpg
Header add Content-Disposition "attachment" env=requested_jpg

    Not sure if that helps?

<head>
<title>Your title</title>
</head>
<body>
<form><input type="button" value="Click Me" onClick="window.location.href='image.jpg'"></form>
