Support a tag to post pictures to Facebook from an RSS feed (for example: meta property="og:image")
This tag is supported by the Open Graph protocol: http://developers.facebook.com/docs/opengraph/
Interesting suggestion. We’ll examine this further.

This is a must. Only thing that keeps me using Twitterfeed for RSS-updates to my Facebook-pages. Make this happen and I'll be using only Ow.ly -platform!
