I've got a site (password protected, sorry) where I have this in the
top of my template:

session_start();
$iSessionId = session_id();
$iSessionName = session_name();

Then I have a bunch of links like this in the site:

echo "<a href=\"/departments/\">Departments</a>";

The first time, and only the first time you load the page, that link
is transformed in the HTML output to be this:

<a href="/departments/?
PHPSESSID=4aec641b497131493b1c4bf489def723">Depart ments</a>

But if I reload the page, or go to any other page, I will get this:

<a href="/departments/">Departments</a>

which is what I want. Obviously I could do something where if it
detects the PHPSESSID in the URL, it forces the page to reload, but I
was thinking that there would be another way to do this without
adding another page load into the mix. Is there?

These are caused by the php.ini setting session.use_trans_sid being on.
This setting allows sessions to work when are disabled.

http://php.net/ref.session#ini.session.use-trans-sid

I'm not sure why you have such a problem with it. Why is it important
that the URL does not contain the session ID?

Anyway, the way to "fix" it is to disable that php.ini setting.

From your above examples, two questions come to mind:
1.) Is thumb.php in a folder above `data`? If not, adjust
your path accordingly.
2.) When using the query ?filename.jpg are you going to call
that as an $argv[1] variable? If you want to use it as a $_GET,
$_POST, or $_REQUEST, it will need a variable name with an assigned
value. For example:
<img src="thumb.php?img=filename.jpg">
L>thumb.php
<?
$path = "../data/original/"; // In case it's a same-level
directory as the PWD
$img = $_GET['img'];
header("Content-type: image/jpg");
readfile($path.$img);
?>

Give a man a fish, he'll eat for a day. Then you'll find out he was
allergic and is hospitalized. See? No good deed goes unpunished....

thank you Mr. Brown for your reply,

yep thumb.php and img.php are in the same level

correction for img.php
<img src="thumb.php?url=filename.jpg" />

i don't know what wrong with it, when i save the image data to another
files, the image didn;t corrupted, but when displayed dynamically it's
corrupted.., and the path are ok

did i miss something on this, and i didn;t aware of it ?

Rather than viewing img.php, go directly to thumb.php?filename.jpg in
your browser. Change the content-type to text/plain and see what you get
in the browser.

You may also want to remove the ?> at the end of thumb.php - it's not
needed and may be adding whitespace to the image you are returning.

Change
header("Content-type: image/jpg");
to
header("Content-type: image/jpeg");

Apparently IE doesn't like image/jpg [1].
