meta data needed for logo on facebook

Issue Summary

Referring to the FaceBook instruction, if we want to upload a logo along with the shared text, we need a specific meta name and link in the page header.

Isn't there an option to manage uploading logos automatically to the various sharing sites ?

or do we need to include special metadata for all sites for logos ?

(in case I'm not clear, this is my site : mylifeblows.net if you click on a facebook share link you'll notice the blue logo included, but i had to manually add meta data to my page.tpl.php. Is there is an option to do that automatically or should that be a feature request ?)
