Error creating thumbnail!

[quaqua]

I use 4images for a wallpapers site. I've uploaded bulk wallpapers packs but there's a problem - not all have thumbnails.

When i try to use auto-thumbnailer to create thumbs i get this error:


Create thumbnail for: Bleach (140) (Bleach (140).jpg) ....  
Warning: imagecreatefromjpeg() [function.imagecreatefromjpeg]: gd-jpeg, libjpeg: recoverable error: Premature end of JPEG file in /home/wallpapers/domains/doamin.com/public_html/includes/image_utils.php on line 80

Warning: imagecreatefromjpeg() [function.imagecreatefromjpeg]: './../data/media/517/Bleach (140).jpg' is not a valid JPEG file in /home/wallpapers/domains/domain.com/public_html/includes/image_utils.php on line 80

   Error creating thumbnail!


Create thumbnail for: 485 (485.jpg) ....  
Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 24000 bytes) in /home/wallpapers/domains/domain.com/public_html/includes/image_utils.php on line 80



What can cause it ? How to fix it ?
I'd like to have thumbnails for all of the images on the site..

Hello and welcome to 4images forum.

The first two lines look like there is a corrupted image
The last error indicates that there is not enough server allocated memory to create thumbnail for that image. (more info: FAQ -> Fatal error: Allowed memory size of NN bytes exhausted and if you want get little more technical info: Thumnail error)
