The following error is showing up at the bottom of my admin pages since installing this plugin:

Notice: Undefined index: post_type in …/plugins/quick-product-image-upload/quick-product-image-upload.php on line 40.

I have few question, pl clarify.
1) Not able to upload multiple images. Can select only one
2) Product image – does it mean – feature image or product gallery
3) Uploaded image – will it be added to product gallery?
4) Can it support custom post types
