When I attach an image with mybb attachment function

the image file is not cached and is loaded every time I load the page.

This is a waste of traffic

Can an attached image be cached?

So I do not know if the image is cached. 

image of the attachment in the post be cached?

I am not aware of any images ending in .php. 

.php is a source hypertext file, not an image.

So I do not know if the image is cached. 

image of the attachment in the post be cached?

Ok, do you have the Attachments setup in your AdminCP like it's shown in the screenshot below?

One of the MyBB experts should be able to assist you. 

I am not certain what else it can be.

Compared to imgur,
uploaded Images with mybb attachments are loaded every time when I click F5. Not cached

---

$img = $mybb->settings['uploadspath']."/".$attachment['attachname'];

$time_up = $attachment['dateuploaded'];
$etag=md5($time_up.$img);
$time=gmdate('r', $time_up);

header('Last-Modified: '.$time);
header("Cache-Control: must-revalidate");
header('Expires: '.$time);
header("Etag: ".$etag);

I seem to have found a way.
Attaching this header to image in attachment.php will cache it.
