This is one of the best written plugins I've ever used, so first off, thank you for such an awesome and useful plugin.
I was trying to manually place the "Edit" button for one of my theme images, because the floating default one doesn't work due to another image overylaying it. But when I manually place the edit button it doesn't properly call the thickbox to edit the theme image. Here's an examle of a testcode I used:
<div class="fee-group"><div class="fee-buttons"></div>
'fb', '/wp-content/themes/actors/images/icons/facebook.png', array(
'width' => 64,
'height' => 64,
'alt' => 'Facebook'
