Should I post this in Bug Tracker?
I have turned on Grayscale Thumbnails in the Theme Options page. Some Thumbnails REFUSE to generate in grayscale. I have manually deleted the cache, regenerated the cache from the admin page, allowed ZP to do it upon a user viewing a page. Some thumbs simply refuse to gen in grayscale :-(
As an example, please see my web site above. The Floyd Bennett Field album is one example, it's album thumb is always in color and then in the gallery itself, the Capital Airshow gal for example, one image thumb refuses to generate in grayscale.
Thanks for your help.
