Error category-images-ii.php on line 267

Hello, I am using the latest cry of wordpress which I think is 3.01

Any way, I get the following error.
[code]

Warning: getimagesize() [function.getimagesize]: Filename cannot be empty in /home/hispanic/public_html/mywebsite.com/wp-content/plugins/category-images-ii/category-images-ii.php on line 267

Warning: Cannot modify header information - headers already sent by (output started at /home/myserver/public_html/mywebsite.com/wp-content/plugins/category-images-ii/category-images-ii.php:267) in /home/myserver/public_html/mywebsite.com/wp-includes/pluggable.php on line 890

[/code]

How do I fix this?
