passing many variables to image.php 2

[elck]

Hi all.
I want to create a graph with loads of information.
How would you pass those variables to the image?

It seems that sessions do not work for images?

What I use now is something like this:

print "<img src='image.php?var1=1&var2=2....&var1020=1020' >";

but there is a limit to the number of variables that can be passed in this manner.
Do you guys (&galls) have any smart ideas?

You says sessions don't work. Can you elaborate >, they shoud as all your doing is requesting a page, its just outputs image/jpg rather than HTML.

could be a register_globals thing, is image.php aware of what the $_GET[] values are ?

Say if you just call

http://somehost.com/image.php?var1=1&var2=2....&var1020=1020

what output if any do you get?

I think you are both right here.

I had read something somewhere, then when I did not get the expected results I assumed that the <?header ("Content-type: image/png");?> destroyed the session variables.

In a new test file I get the desired result this way:

session_start();
$_SESSION['test']="a lot of data";

in the image.php this works fine:

session_start();
header ("Content-type: image/png");
[....]
imagestring ( $im, 4, 10, 10, $test,$black );

Thanks,ingresman and karver
