Hi, I have a error in webmastertools for the images sitemap. Widgetkit gallery puts them in the cache. I tried to make the cache accessible in robots.txt but still got the error.

User-agent: *
Disallow: /administrator/
Disallow: /bin/
Disallow: /cache/
Allow: /cache/widgetkit/
http://www.soukz.nl/index.php?option=com_jmap&view=sitemap&format=images

<image:loc> http://www.soukz.nl/cache/widgetkit/gallery/40/Hamamdoeken-3-edb62fb22c.jpg
</image:loc>
<image:title>Hamamdoeken-3</image:title>
</image:image>
</url>

How can I make google indexing all the images from the gallery's?

Regards,
Raoul
