[Plugin: Auto Post Images (API)] How to set uploaded images as featured images

Hi. Thanks a lot for the plugin.
This way of uploading a bunch of images and automatically linking them to posts by slug names makes it easy to manage the posts – especially when using csv imports for the post contents.

However I still got a serious problem. How might it be possible to automatically set the uploaded image per post as “featured image” of the post in wordpress. Once that is done, many themes would work since they rely on the thumbnails of the featured images. Thank you so much for any help.

Until now I do not get the images shown wihtin the loop but only per post. This struggle should also be solved once the featured image per post is set.

The solution of that would defenitly be worth a donation.
Appreciating your work.
Thank you, henrik
