Custom error image at thumbs creator

[danny]

Thank you very much for your wonderful script! Do you know how can I replace an error for a custom image?

For example if the image is not specified or found.

if (isset($_REQUEST['src'])) {
  $from_name = urldecode($_REQUEST['src']);
}
else {
  die("Source file name must be specified.");
}


Thank you =)

Do you mean show custom image instead of error message?

Replace
die("Source file name must be specified.");

with
header("Content-type: image/gif");
readfile('/here/path/to/your/custom/image.gif');
die();

This is for custom error image of GIF type.

If you custom error image is JPG then replace image/gif with image/jpeg.
If you custom error image is PNG then replace image/gif with image/png.

Hi Zubrag, thank you for your reply. yes, I want it show an image when an incomplete action is typed: http://domain.com/pics/thumb.php?src=    but I get this error...

Warning: getimagesize(): Read error! in /home/host/public_html/pics/thumb.php on line x
Image type not supported

My readfile is the same $images_folder


if (isset($_REQUEST['src'])) {
  $from_name = urldecode($_REQUEST['src']);
}
else {
  header("Content-type:image/jpg");
  readfile('/home/host/public_html/pics/image.jpg/');
  die();
}

Best Regards   =)

Changed code. Note: also removed / after the image name.

if (isset($_REQUEST['src']) && trim($_REQUEST['src']) != '') {
  $from_name = urldecode($_REQUEST['src']);
}
else {
  header("Content-type:image/jpg");
  readfile('/home/host/public_html/pics/image.jpg');
  die();
}

Hi !
I made the changes but I got this error:

Parse error: syntax error, unexpected ')' in /home/host/public_html/pics/thumb.php on line 68

if (isset($_REQUEST['src']) && trim($_REQUEST['src']) !=) {
  $from_name = urldecode($_REQUEST['src']);
}

Thanks !

You missed two single quotes before closing bracket. It should be
if (isset($_REQUEST['src']) && trim($_REQUEST['src']) != '') {
