SWFupload and Rails 3

He Guys!

I have a problem with swfupload and have been on it for hours! .. i have
no hair left on my head !
i am trying to get the swfupload working with rails 3

Of course i am able to upload with a simple file_field.
also I am using paperclip (which works just fine).

But when I try to upload images with swfupload i get 404 errors
my log tells me: No route matches "/images/create"

does anybody know what i am doing wrong ?
I think it has something to do with the mime-type but shouldn't it give
me an other error ?

Thanxs
