I love the plugin you've created for WordPress to Buffer. I'm wondering if you can help me with something... it seems to pick an image from the page when posting, but it's not the one I would prefer. Is there a way to configure it to always use the same image if one isn't present in the post? In other words, if I don't have an image in the post (text only or video post) and I don't set a featured image, am I able to configure a default image, which might be my site logo or my own head-shot? Thanks!
