Multiple File Upload with attachment_fu

I have been trying to implement a multiple file upload page for
uploading photo’s. My single upload page works without problems. I
tried to use the aurigma image uploader (as used by facebook, geni,
etc.). I had it working fine when i was using the flex_image upload
plugin but once i moved to attachment_fu (which i prefer because of
its amazon support), multifile upload fails when trying to store the
model object that is declared as has_attachment.

Has anyone had any experience with using other multiple image upload
controls? or does anyone know what my problem may be. I think it has
something to do with the image encoding peformed by aurigma which may
conflict with the backend work being done by Rmagick in attachment_fu
