@madalin: Thanks! It’s working now.
I was searching for this: <img src="<?php the_cfc_field('my_meta_name', 'avatar'); ?>" />

I now have an upload field for a specific post.
I configured it at the custom fields creator.

There is a field called “post id” under meta box arguments. I can fill in the ID of a post on which the meta box should appear.

How do I add this custom field to multiple posts? Or even better; add it to posts in a specific category?

I now have to fill in a specific ID of a post on which the meta box should appear. I want to know if it is possible to add the custom field to all posts by default, instead of one specific post?

Thanks in advance!
