Nice tool, anyone tried it?

I am using it for my wife's self-hosted wordpress blog.

Wordpress has native rss support, so creating LIVE tiles should be easy. And it is. But I have a problem with images for live tiles.

My xml data for feed is here: using this links to create xml code for LiveTile:

Everything is fine, but my rss xml file (first link) is not providing image data for the tile (from featured image).

Do you know guys if can create image thumbnail images from rss at all? If yes, which metatags should I use in rss xml file for to be interpreted as liveTile image?

If tool is not able to display images, I can of course generate custom xml file for live tiles in Wordpress, but I find first solution much simpler.

Any thoughts?
