The image is created in php gd. Thanks.

 

 

picture.php

 

<?php  

header('content-type: image/jpeg');

$image = imagecreatefromgif('emp.gif');  
$size = getimagesize('emp.gif');  

$strings = $_GET['strings'];

$len = strlen($strings);
$cur = 0;
$characterarray = array();
while($cur < $len){
$char = $strings{$cur};
array_push($characterarray,$char);
$cur = $cur + 1;
}

/* "*---*"  "      --" */

$car1 = imagecreatefromgif($characterarray[0].'.gif');
$car2 = imagecreatefromgif($characterarray[1].'.gif');
$car3 = imagecreatefromgif($characterarray[2].'.gif');
$car4 = imagecreatefromgif($characterarray[3].'.gif');
$car5 = imagecreatefromgif($characterarray[4].'.gif');
$car6 = imagecreatefromgif($characterarray[5].'.gif');
$car7 = imagecreatefromgif($characterarray[6].'.gif');
$car8 = imagecreatefromgif($characterarray[7].'.gif');


  $dest_x = 17;
$dest_y = 33;
$dest_x1 = 17;  
$dest_x2 = 43;  
$dest_x3 = 69;  
$dest_x4 = 95;  
$dest_x5 = 121;  
$dest_x6 = 147;  
$dest_x7 = 173;  
$dest_x8 = 199;  

imagecopymerge($image, $car1, $dest_x1, $dest_y, 0, 0, imagesx($car1), imagesy($car1), 100);
imagecopymerge($image, $car2, $dest_x2, $dest_y, 0, 0, imagesx($car2), imagesy($car2), 100);

imagejpeg($image);

$filename =

    if (is_file($filename)) {
        readfile($filename);
        exit;
    }

imagejpeg($image,$filename);
  
imagedestroy($image); 

imagedestroy($car1);

you will need to include the full URL to the page, eg http://somesite.com/picture.php?string=123

in your img = src tags.

So like when you go to picture.php you see gibberish?  You don't see English text or anything, just gibberish (like if you opened an image in notepad)?

 

That most likely means that the header isn't processing correctly.  As for why it wouldn't work correctly in an img tag, I have no idea....

[Ravo]

I agree with Corbin. I used to do that all the time and incorrect headers will completely kill the whole image.

[SkyRanger]

I don't know much about image headers but wouldn't this be the problem:

 

header('content-type: image/jpeg');


shouldn't it be:
header('content-type: image/gif');

If he is trying to process a gif image and not a jpg or jpeg image

[corbin]

You can make any kind of image from any kind of image in PHP, and he's out putting a jpeg.

imagejpeg($image);

 

It might have something to do with the "content-type", but I don't think headers are case-sensitive...
