$destimg=ImageCreate($new_width,$new_height) or die("Problem In Creating image");

$srcimg=ImageCreateFromJPEG($im) or die("Problem In opening Source Image");

imagecopyresized($destimg,$srcimg,0,0,0,0,$new_width,$new_height,ImageSX($srcimg),ImageSY($srcimg)) or die("Problem In resizing");

Oh, sourceforge uses linux, so it doesn't use dll files.

Ask the admin's if there php version was compiled with gd support.

"Is php on your servers complied with gd?"

Or just put this in a file and see for your self

code:

<?phpinfo();?>

Check what version they have.

Amailer · **Posted:** Sun Nov 02, 2003 6:27 pm

avatar is a folder... C:/Program Files/Apache Group/Apache2/htdocs/img/Avatar/

octopi · **Posted:** Sun Nov 02, 2003 6:35 pm

Post the whole code, cause you can't expect me to find a problem when you only post a small part of it.

Amailer · **Posted:** Sun Nov 02, 2003 6:38 pm

code:

<?
function getRandomImage($dir,$type="random")
{
global $errors,$seed;

if (is_dir($dir)) {

$fd = opendir($dir);
$images = array();

while (($part = @readdir($fd)) == true) {

if ( eregi("(gif|jpg|png|jpeg|bmp)$",$part) ) {
$images[] = $part;
}
}

// adding this in case you want to return the image array
if ($type == 'all') return $images;

if ($seed !== true) {
mt_srand ((double) microtime() * 1000000);
$seed = true;
}

$key = mt_rand (0,sizeof($images)-1);

$im = $dir . $images[$key];

header("Content-type: image/jpeg");

$new_width = 90;
$new_height = 90;

$destimg=ImageCreate($new_width,$new_height) or die("Problem In Creating image");

$srcimg=ImageCreateFromJPEG($im) or die("Problem In opening Source Image");

imagecopyresized($destimg,$srcimg,0,0,0,0,$new_width,$new_height,ImageSX($srcimg),ImageSY($srcimg)) or die("Problem In resizing");

ImageJPEG($destimg,$im) or die("Problem In saving");

imagedestroy($im);

} else {
$errors[] = $dir.' is not a directory';
return false;
}
}

$dir = "./img/Avatar/";

getRandomImage($dir);

?>

In the images/avatar folder there are 3 images:
theonetokill-avatar.jpg
OneToKills2.jpg
admin-avatar.jpg

Basically it displays randome images that have been resized to 90x90 px

octopi · **Posted:** Sun Nov 02, 2003 6:40 pm

Does images[] have any values.....if it doesn't then the program would just goto the Dir specified...and might try to add a .jpg extention to it. That would explain your error in the logs.

Amailer · **Posted:** Sun Nov 02, 2003 6:49 pm

It does, it works prefectly with out creating an image, ill show you.

code:

<?
function getRandomImage($dir,$type="random")
{
global $errors,$seed;

if (is_dir($dir)) {

$fd = opendir($dir);
$images = array();

while (($part = @readdir($fd)) == true) {

if ( eregi("(gif|jpg|png|jpeg|bmp)$",$part) ) {
$images[] = $part;
}
}

// adding this in case you want to return the image array
if ($type == 'all') return $images;

if ($seed !== true) {
mt_srand ((double) microtime() * 1000000);
$seed = true;
}

$key = mt_rand (0,sizeof($images)-1);

$im = $dir . $images[$key];

header("Content-type: image/jpeg");

$fs = fopen($im, 'rb');
fpassthru($fs);
exit;

} else {
$errors[] = $dir.' is not a directory';
return false;
}
}

$dir = "./img/Avatar/";

getRandomImage($dir);

?>

that way it works,
But, the other way it don't.

Didn't you say $im was just a path name, and not an image resource?

Do you understand what imagedestory() does?

Amailer · **Posted:** Sun Nov 02, 2003 7:53 pm

the $im has the the image (eg. ./img/avatar/image.jpg)

Either way, with and without the imagedestory() it does not work :SS:S

octopi · **Posted:** Sun Nov 02, 2003 10:57 pm

Well...you were using imagedestory wrong...

Look at your error's its telling you the problem...your trying to open a Jpeg image, that isn't a jpeg image.

Theres nothing else I can do....you should check the paths, and stuff, and see exactly where its looking for the file, before you try and show the image.
