Hello all,
Following up with my success last week with putting downloadable files
in a directory above the web root and then using a combination of fopen
and stuff to download the file, I am now trying to do something similar
with images.
However, what I am trying to do is to put an image file above the web
root, then use PHP to display that image in the web page, and not
download it. I have the feeling that this isn't possible (all solutions
I've seen involve using header() function, which won't work since this
is midway down the page), but I wanted to make sure. This will return
the binary source of the file:
print file_get_contents($file_path);
but doesn't display the image. Is there any way to have this (or
something else) generate the image?
You need to have a separate file that you link to like you would for the image, then that file must
send headers and the binary contents of the image to the browser. You cannot send the image data
with the HTML data.
have a link in your image tag like this. <img src='image.php?img=something.jpg' />
then in the file image.php it sends headers like this:
<?php
$image_folder = '/path/to/images/';
$file = $images_folder . basename($_GET['img']);
$imagedata = @file_get_contents($file);
$length = strlen($imagedata);
header('Last-Modified: '.date('r'));
header('Accept-Ranges: bytes');
header('Content-Length: '.$length);
header('Content-Type: image/jpeg');
print($data);
exit;
?>
This is a quick example that was put together out of information from the header and readfile &
passthru pages in the manual
