PHP：如何从磁盘输出到浏览器的png图像？

Question

I've a file on a folder on disk I don't want to be visible from web browser

So i create an image.php file that take a file name and must 'do echo' to browser of the image.

Example:

mysite.com/image.php?name=selection.png

must show an image to the user into the browser.

Actually browser ask me to save. I want to show it, not do ask to download...

i'm using this snippet

header("Content-Type: image/png");
header('Content-Length: ' . filesize($full_file_name));
header("Content-Disposition: inline; filename='$image'");
readfile($full_file_name);
exit(0);

if saved and opened, img is perfect. How to NOT ask to download it?

EDIT

• Yes, i need something to use into image tag

Most of you are replying to my question telling me about image creation, but my question is all about different mode to tell to browser to show something and to ask to user to save something. NO MORE REPLY ABOUT IMAGE CREATION - YOU'RE OFF-TOPIC !

Probably my question, my title, is not clear, but my question is simple:

- How to tell to browser to SHOW an image insted to ask user to save it

Image creation is working

Image usage via imag src is working

**But when user clicks on image, a new tab is opened with the images src as link, because I need to show full size image into browser. In this situation browser ask me to save !

EDIT:

Removing

header("Content-Disposition: inline; filename='$image'");

doesn't change Firefox behaviour

Answer 1

try;

header("Content-type: image/png");
passthru("cat $full_file_name");
