I use for create the thumbnails GD Bibliothek (4image 1.7). When I auto-create the thumbnails and resize the images the program give me error:
Create thumbnail for: Michael Wentink & Beata (South Africa) (Mb_1.jpg) ....
Warning: imagecreatefromjpeg: './../data/media/10/Mb_1.jpg' is not a valid JPEG file in /home/dance/dancesport-www/4images/includes/image_utils.php on line 71
Error creating thumbnail!
How can I solve this problem?
Thank you.
