Re: [PHP] TIFF display problem...
Are you certain there are no other characters being sent (introduced
by the addition) in the 'body' beside the image?
Will you get any output (characters and all) if you request the image
file directly - without embedding it into a page using img src or
whatever?
While I have used only the supported by default images like jpg, png
and the like, that always turned out to be the problem for me ...

Hi All,
I've run into a jam.. I have the follow PHP script:
?
header(Content-type: image/tiff);
$_GET['id'] = str_replace( ., , $_GET['id'] );
$_GET['id'] = str_replace( /, , $_GET['id'] );
$blah = /usr/local/apache/chm-images/ . $_GET['id'] . .A;
readfile( $blah );
?
This works just fine...
When I add...
session_start();
if ( !$_SESSION['user_id'] )
{
exit();
}
...to it, the image does not display.
What I need to do is read in images from a secured directory and display it
on the page. I was using JPGs before and now need to display TIFF files.
We have the plugins for IE all setup. Could someone tell me how I could fix
this? I'm at a complete loss...

Argh, I see your problem was already solved (answers haven't been
listed as one thread, so I missed em). Oh well.

Hi,
Yeah, positive, I should probably clarify more. session_start(); is
what causes it not to display, and gives me the error. The error is that
the site cannot download the file.

Hi,
that probably would work better, however, the if control isn't
what's fouling it up. I can omit that and leave session_start() in there,
and its fouled up. Session_start() is the culprit.

Do you have a temp directory setup for your session variables?

Hey Matt, That was the trick, thanks.. I passed that function... what is it... session limit cache something or another. Worked like a charm!
