I'm trying in this front-end Gravity form to allow the user to upload a few "additional images".
I've created a Metabox field group for posts, and one of the fields is the "Image Advanced" field.
In the GF form editor I've added a "Post Field", used the type "File Upload", and mapped the field to the Metabox field ID.
When submitting the form the additional images get submitted to GF, but they don't appear in the post, and also not in the Media library.
What am I doing wrong?
