file extension

[mehmetalikus]

When i want to download my barcode its downloading as barcode.PHP. so this file extension may not effect us but there are other people who don't know how to change file extension. so add this line inside function output_image
for example:
case "png":
header('Content-Disposition: attachment; filename="anything.png"');

This will make browser to download file immeadiately. And there for I think this isn't intention of this function.

It's possible to make download_image function with this header 😄
