You catch click event of Save button, then open url of download page. See following codes:

<input type='button' value='Save' onclick="location='http://yourhost/forcedownload.php';" />

Code (markup):

 

<a href="savebuttonfile.php" target="_blank"><img src="savebutton.png"></a>

Code (markup):

Why could you not just do it like this? You would have the force download in the .php file. It would open up another window so perhaps a javascript onlick event would be better as dthoai said.

 

Save the following code in a file - download.php on your server. Run it with appropriate URL.

<?php
if(isset($_GET['download']))
{

// force to download a file
$file = "http://localhost/test/image_file_name.jpg";

header("Pragma: public");
header("Expires: 0");

header("Content-Type: application/force-download");
header( "Content-Disposition: attachment; filename=".basename($file));

header( "Content-Description: File Transfer");
@readfile($file);

}
else
{
?>
<form method="get" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<input type="submit" name="download" value="Download File" />
</form>
<?php
}
?>

PHP:

Ensure that the if() part inside the PHP code doesn't output any blank space (whitespace) apart from the image file.
