How to use Plupload on an image field in a content type

Hi !

I've created a new content type "Gallery" in wich I add an "image" field.
I've installed Plupload module, and then "FileField Sources" and "FileField Sources Plupload", but when I create a new Gallery, I can't get the Plupload widget.

In Media, when I choose "add file" the plupload widget works, but not in my content type.

I've try to change the image field widget, but I only have choice between "image" and "media file selector", neither of them works with Plupload.

Did I miss something, or is this module not made to works with simple image field ?

Thanks
