i have edited my php.ini for php_gd.dll and apache works fine but when i call <img src="button.php?text"> my page cant draw the image but gives no parse error.

here is my button.php

<?php
Header("Content-type: image/png");
$string=implode($argv," ");
$im = imageCreateFromPng("images/button1.png");
$orange = ImageColorAllocate($im, 220, 210, 60);
$px = (imagesx($im)-7.5*strlen($string))/2;
ImageString($im,3,$px,9,$string,$orange);
ImagePng($im);
ImageDestroy($im);
?>

any suggestions? thanks

    This one got me aswell, i assmued the header for png would be...

    Header("Content-type: image/png");

    but i the browser rejected it, so i tried...

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

    This worked, no doubt someone will tell me im wrong but it worked for me and displayed the png image

      i m afraid that doesnt work for me...any other suggestions?

        Your code looks fine, i would double check this line though

        $px = (imagesx($im)-7.5*strlen($string))/2;

        I was getting something similar when working with sizing it could be that, i don't really know...

        First of all check the GD Library dll was loaded using phpinfo();

        Then check your version of the GD Library supports the png image type because some builds don't support it

          gd is loaded (version 2.0) and png is enabled.

            and what is the error that you get?

              Are you calling the script like so

              <img src="button.php?text=<? echo $text; ?>"

              Mark

                no error, just the image is not displayed in page, in ie i get the box with the red x, just like when an image is not found. can u help?

                  no i am calling it <img src="button.php?text"> . i am still testing it so i just want to display the word "text" on an image...

                    it asks me to open from current location or save...when i choose open from current location it opens imageready but the latter fails to open the file. any ideas?

                      comment out the image-headers for debugging, see what the script says.

                        button.php :
                        <?
                        //Header("Content-type: image/png ");
                        $string=implode($argv," ");
                        $im = imageCreateFromPng("images/button1.png");
                        $orange = ImageColorAllocate($im, 220, 210, 60);
                        $px = (imagesx($im)-7.5*strlen($string))/2;
                        ImageString($im,3,$px,9,$string,$orange);
                        ImagePng($im);
                        ImageDestroy($im);
                        ?>

                        http://localhost/button.php?text gives:

                          problem solved I guess? 🙂

                            my quess is that there is a problem with the gd library cause the code is from the manual. what could i do if phpinfo says that gd library is ok?

                              Well, my guess is that you are trying to access a file that does not exist, or that has a different name or location.
