PHP readfile for force downloading files and images

Question

I want to send files through php using readfile()

What i've noticed is that readfile forces a download, but what if i want to show an image in the browser and not force a download?

Would readfile still force download even if the file is an image?

If it does, is there a solution so i can use tags with it when the file is an image?

Thanks!

You need to set the MIME type with the header() function. There should be info in the comments. Something like:

<?php
header('Content-type: image/png'); 
?>
