[Plugin: Auto Image Resizer Lite] convert my images into grayscale

Hi.

This plugin looks very promising, but the “convert my images into grayscale”option is enabled though it says this feature is only available in the PRO version and I’m unable to disable.

Your help would be much appreciated as the plugin isn’t very useful (to me) converting my color photos to grayscale. Thanks!
