This is the item from the feed I'm currently experimenting with:

Everything except the image seems to work, I've enabled the "featured image" add-on but it doesn't download the image in <url> nor does it set it as the featured image.

This is the reason I got autoblogged - what can I do to make it work as intended?

Best regards,
