Image Errors when uploading.

[the_error_king]

When I am adding a new product, and I try to upload an image and hit "preview," it seems to work except it takes quite a while longer than usual to upload, and I get these errors at the top of the page:

Warning: imagecreate(): Invalid image dimensions in /home/lorelei/public_html/catalog/admin/includes/classes/upload.php on line 216

Warning: imagecopyresized(): supplied argument is not a valid Image resource in /home/lorelei/public_html/catalog/admin/includes/classes/upload.php on line 217

Warning: imagejpeg(): supplied argument is not a valid Image resource in /home/lorelei/public_html/catalog/admin/includes/classes/upload.php on line 269

Warning: chmod(): No such file or directory in /home/lorelei/public_html/catalog/admin/includes/classes/upload.php on line 119

anyone know what I need to do to correct this?

Does the directory have the right settings?

Can osCommerce write to that directory?
Is you disk space full?
