This Extra Field Type is available in Profile Builder 2.0, Hobbyist or Pro.
You can use this extra field type to allow users to upload their Avatar.
You can specify the field title, meta-name to be stored in the database, description, allowed image extensions and avatar size.
You can opt for using a simple upload field instead of the WordPress one.
Also, you can set whether this field should be required or not.
This is how it looks like in the front-end.
