Thumbnail Generation Alert!

Sorry, I’m not familiar enough with WP to suss this one out and need some assistance. The galleries appear to work correctly, however, I’m concerned with the error (provided below) that I’m receiving. I’ve gone through the troubleshooting steps, including disabling all other plugins and reverting the theme back to the original to make sure there are no conflicts with no change in the error message.

Within WordPress, I’m seeing the following when navigating to the FooGallery menu option:
Thumbnail Generation Alert!
There is a problem generating thumbnails for your galleries. There could be a number of reasons which could cause this problem.
If thumbnails cannot be generated, then full-sized, uncropped images will be used instead. This will result in slow page load times, and thumbnails that do not look correct.

Running the Thumbnail Generation Test returns the following:

Thumbnail generation test failed!object(WP_Error)#3328 (3) { ["errors"]=> array(1) { ["image_no_editor"]=> array(1) { [0]=> string(28) "No editor could be selected." } } ["error_data"]=> array(0) { } ["additional_data":protected]=> array(0) { } } array(2) { ["ext"]=> string(3) "ico" ["type"]=> string(12) "image/x-icon" }

Clicking on the "View Thumb Test Page" link, returns the following errors (along with what appears to be successful operations). I've verified that the test files exist.
