Can’t display image in jpg format

[eluser]Wangringring[/eluser]
I've got a problem about display image in CI.
I don't want to use <img> tab to display image.
Does it have any library in CI?
I just want to display an image. I try to use image_lib() but it didn't work too.

Now I'm trying to use simple code to display image.
My code in View is like this

Code:

header("Cache-control: private");
header("Content-Type: image/jpg");
header("Content-Disposition: inline ;filename=arnon.jpg");
$fn=fopen("images/arnon.jpg","r");
fpassthru($fn);

but It displays not an image. It likes many ramdom-text and special characters like this:

Code:

Oฝฎดs]r๒#๗ฝ=?ถฒณด#๏ฐP% ๋ต˜# ชฒ?๓โมมฌ ‰#JFIF###HHํ Adobe_CM#๎#Adobed€#„ ### # # ### ########## # # # ################

Could anyone suggest me please?
