<b>Fatal error</b>:  Call to undefined function:  imagecreatefromjpeg() in <b>/blabla/sig.php</b> on line <b>27</b><br />

where line 27 is

$im = imagecreatefromjpeg($logos[$logo]);

]the code I use right now looks like this: (just making sure we are talking about same script and same things)

<?php
$logodir = "http://www.somewhere.com/pics/";

header('Content-Type: image/jpeg');
header('Content-Disposition: inline; filename=file.jpg');
header('Cache-Control: no-store, no-cache, must-revalidate');
header('Pragma: no-cache');

$logos = array
(
    $logodir . "1.jpg",
    $logodir . "2.jpg",
    $logodir . "3.jpg",
    $logodir . "4.jpg",
    $logodir . "5.jpg",
    $logodir . "6.jpg"
);

function make_seed() {
    list($usec, $sec) = explode(' ', microtime());
    return (float) $sec + ((float) $usec * 100000);
}
srand(make_seed());

$logo = rand(0, count ($logos) - 1);

$im = imagecreatefromjpeg($logos[$logo]);
Imagejpeg($im);
imagedestroy($im);

?>

hmm, look here:
http://www.php.net/manual/en/functio...tefromjpeg.php

its a standartfunction in php.
something with your php-installation seems not to be ok...

]I have tried it on 2 servers now... one in Germany and one in Holland. Both are installed by 2 difefrent peoples. Same result - doesn't work

[wooolF[RM]]

]by the way... I don't blame you or something... I really appreciatte all your help... but I can't see meaning of creating an image from an EXISTED image, show it and then destroy it...

why not just push the existed image?

have tried it at my server, works perfect:

i don't know why, its just the way php wants it

hmm, maybe your servers have disabled this function, have tested it on another server too and works perfectly too

]ok... I got my friend to use it on his server (3rd server I'm trying to get it workk on).

It works! yay! now the problem is : all 6 pics I used was 25-30kb in size in perfect quality. After randomizing by this script all I get is blurred, low quality picture 8-9kb in size...

are there any ways to be sure that qulity at the end is the same as in the start?

btw : thanx for this workaround

]Anyway, here's updated version of my script that should at the output generate progressive JPEG with 100% quality.

<?php

/* Location of the pictures */
$logodir = "http://www.mpc.turbohost.net/wolfsig/";

/* Type of output (for browsers) */
header('Content-Type: image/jpeg');

/* No caching (for newer browsers) */
header('Cache-Control: no-store, no-cache, must-revalidate');

/* No caching (for older browsers) */
header('Pragma: no-cache');


/* Making an array with all pictures */
$logos = array
(
    $logodir . "1.jpg",
    $logodir . "2.jpg",
    $logodir . "3.jpg",
    $logodir . "4.jpg",
    $logodir . "5.jpg",
    $logodir . "6.jpg"
);


/* explode = explode an array */
/* microtime = return current UNIX timestamp with microseconds */

function make_seed() {
    list($usec, $sec) = explode(' ', microtime());
    return (float) $sec + ((float) $usec * 100000);
}

/* explode	= seed the random number generator */
srand(make_seed());


/* rand = seed the random number generator */
/* count = count elements in a variable */
$logo = rand(0, count ($logos) - 1);

/* Create image from predefined variables */
$im = ImageCreateFromJPEG($logos[$logo]);

/* Output image as a progressive JPEG */
imageinterlace($im,1);

/* Output image with 100% quality */
Imagejpeg($im,'', 100);

/* Destroy picture on the server */
imagedestroy($im);

?>

As always... Script is working but there's some problems with it : generated pictures are not in the same quality as input pictures.

forget it... I'm using other script
