Can you copy all the code?


Sure, here it is:

<?php
session_start();
$dir = session_id();

if ($_REQUEST['img'])
{
$showfile = "./temp/$dir/".$_REQUEST['img'];

if (file_exists($showfile))
{
header("content-type: image/jpeg");
header('Content-Length: ' . filesize($showfile));
header("Content-Disposition: inline; filename=$showfile");
readfile($showfile);
}
}
echo "<img src='?img=1.jpg'>";
?>

If i keep session_start() "Save picture as" detects image as
untitled.bmp, if i delete
session_start() - everythng is fine, it is detected as jpeg, but i need
session_id(), so i have to start session...
And, i read somewhere in this group that i should add ini_set, like
this:

<?php
ini_set('session.use_cookies', '0');
ini_set('session.cache_limiter', '');
ini_set('session.cache_expires', '');
session_start();
$dir = session_id();
....

When i do that the image type is detected correctly as jpeg, but the
file name is not, its named as the script, showimg.jpg,
filename=$showfile" is not working for some reason. But i guess its
good enough, it would be nice to detect the file name as well though


But earlier you said this really is a bmp, not a jpg.

Just changing the name or header is not going to change the real file type. It
will still be a bmp. If you want to change it to a jpg, you need to convert it
first.

Yes, i understand that. The picture is jpeg (echo "<img
src='?img=1.jpg'>";), but "save picture as" only offered to save it as
bmp, not jpeg, that was my problem/question.
