attachment_fu :thumbnail counter-acting :resize_to

Hey everyone,

In my model i have: has_attachment :storage => :file_system,
                  :content_type => :image,
                  :max_size => 7.megabytes,
                  :resize_to => '1000x1000>',
                  :thumbnails => { :thumb=>'150x100>' }

But what I end up with is two thumbnail sized images. Why is my
original using the thumbnail size instead of the :resize_to size?

The only way to get the original to be the size i want is to remove
the :thumbnails declaration all together. Am I missing something?

thanks
