Hi all,
As a test to understand how to create and save a file on my server i
created the next code:
---
<html>
<head>
</head>
<body>
<?php
$thumb = imagecreatetrue color(100, 100);
Imagejpeg($pic, "pic.jpg");
ImageDestroy($p ic);
?>
<img src="pic.jpg">
</body>
</html>
---
Can anyone tell why the jpeg isn't saved and displayed. Can the
dir-settings be a cause?
Thanx,
WJ 5 10695

You create an image handler $thumb, but then as you call ImageJpeg, you are
using $pic. I wonder if it would help if you used $thumb all the time
instead of $pic (which would be an undefined variable at the time it's
called).

That was a mistake the actual code is :
---
<html>
<head>
</head>
<body>
<?php
$pic = imagecreatetrue color(100, 100);
Imagejpeg($pic, "pic.jpg");
ImageDestroy($p ic);
?>
<img src="pic.jpg">
</body>
</html>

Same problem for that....

I ran this code in my development environment and it worked. I got a page
with a black square 100x100. The image pic.jpg was also saved in the same
directory as the script.
Perhaps your script does not have permission to write the file in that
directory?
Perhaps you don't actually have the GD Library installed? check phpinfo()
for the GD Section - if it isn't there, it isn't installed.
Try this php script: with no HTML
<?php
ini_set( 'display_errors ', '1' );
error_reporting (E_ALL ^ E_NOTICE);
function my_error_handle r ($errno, $errstr, $errfile, $errline) {
echo "In $errfile, line: $errline\n - $errstr<br>";
}
set_error_handl er ('my_error_hand ler');
$pic = imagecreatetrue color(100, 100);
Imagejpeg($pic) ;
ImageDestroy($p ic);
?>
That *should* display errors to the browser if you have any, and they may
let you know why thintgs aren't working.

Almost certainly it is a directory permissions problem. Is this a Unix
(Linux, BSD, wahtever) host? Remember that the web server normally runs
under a non-priveleged user, such as "nobody" or "webuser" or somesuch,
and this user has rather limited write capabilities. Try adding world
writeableness to the current directory:

Changing the permissions solved the problem.

I want to have a field in my form that allow me to paste an image from the clipboard to, for example, a Paint field. Then, I want to save that image to a file on a specific folder in my computer via VB.
The reason for this is that I don't want to ask the user to open paint by himself and save the file, probably in the wrong location and with the wrong name.
