Hello,

I have a sitemap index on my website, which I successfully validated with "Google webmasters tools". The declarations at the top are:

   <sitemapindex xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9 http://www.sitemaps.org/schemas/sitemap/0.9/siteindex.xsd"
         xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"> 

This index lists 2 sitemaps . One of them contains "images" tags after using the http://www.google.com/schemas/sitemap-image/1.1 schema declaration.

When submitting this sitemap index to Yahoo explorer, I get error:

ERROR: FF_30000 “Not an accepted feed format file. Please consult the documentaiton for supported file formats.”

Any ideas?

Joel
