Hello!
I'm hoping someone can help me with this script (thumb_pro.php). It works in IE but in FF, Mozilla and Netscape it creates this error:
"The image “http//www.mypage/thumb_pro.php” cannot be displayed, because it contains errors"
The script is on an intermediate page it is only there to create thumbnails of jpegs that have just been uploaded by the previous page. I put the script on an intermediate page to try and surpress the error.
When I comment out
header("Content-type: image/jpeg");
The error goes away.
Many thanks!
Chris
