Image sitemaps problems (WMT) - Reported as None Indexed

[Mentat]

After this topic [webmasterworld.com] I remembered an old problem: valid image sitemap submitted, none reported as indexed.

Only one subdomain (old sitemaps) are reporting as indexed.
This one is on CDN (subdomain verifid in WMT)

The images are all present in Google Image Search, but not reported as indexed in WMT!

I'm the only one with this problem?

I've checked for robots.txt or nofollow,noindex x-headers.
No problem.

This would mean that in fact the images are indexed, only that WMT is reporting indexed images incorrectly.

WMT is often buggy so if your image is in Image Search, I would not worry too much what WMT says on whether it is indexed or not.

I know, and I have a hunch.
I've modified the sitemaps, waiting for results...

Ok, problem fixed...
What you need to know:

1. The images from the Sitemap must be in the listed page.

This was a problem for me, as the images where listed into a gallery with thumbnails.

Now I list every page of the gallery + the image.

2. If the image is hosted on a different domain (ex CDN), you must have that exact domain/subdomain verified in WMT.

Problem fixed!
