I don't know if this is technically possible, but currently the options for posting to facebook are unable to render a large photo on the timeline - i.e. the posting process doesn't actually add a photo to the wall, but posts a link and facebook creates a thumbnail. Similary, the option to post as an "update" posts title & body content, but (in my case at least) doesn't post an image.
In contrast, when I send an image from a zenfolio gallery, it posts the photo to the wall directly, resulting in a more impressive posting on the facebook timeline. I'm wondering if it's possible for dlvrit to exhibit this same behaviour - it would be a godsend for photographers and creative types :-) to take full advantage of facebook timeline display.
