My images were well indexed when I did not have the "noindex" tag on large image pages
Yes that is infact my question to you. Why should google images bot obey "noindex" tag when they have a separate "noimageindex" meta tag. My understanding is "noindex" is only for not indexing and displaying image attachment pages in google search and not for google image search.
You have not answered my question on whether you have blocked referrers other than Googlebot in your .htaccess file?
I also ran a google bot test from webmaster tools and for direct image links I get "Allowed" for googlebot, even fetch as google worked.
WMT tool only tests crawlability and not indexability.
