Thanks for this Kyle, I was also looking all for this fix.
Here is the the one that I haven’t been able to fix.
I would like to set the default to image instead of none.
Post Meta > Thumbnail Options > Post thumbnail type > (choices are none, image, video, slider)
I tried changing the meta-boxes.php ‘std’ to ‘Image’ but that didn’t do it (see php settings below)
// THUMBNAIL TYPE
array(
‘name’ => ‘Post thumbnail type’,
‘id’ => “{$prefix}thumbnail_type”,
‘type’ => ‘select’,
‘options’ => array(
‘none’ => ‘None’,
‘image’ => ‘Image’,
‘video’ => ‘Video’,
‘slider’ => ‘Slider’
),
‘multiple’ => false,
‘std’ => ‘Image’,
‘desc’ => ‘Choose what will be used for the post item thumbnail.’,
