Hi,

Has anyone any suggestions on whats going on here.

when ever I attempt to upload an image the following error message is  
returned  
“Size is not included in the list”

I have tried different settings in my model, but am not sure whats going  
wrong.

here is my photo model

class Photo \< ActiveRecord::Base

```
#plugins
has_attachment :content_type => :image,
                :storage => :file_system,
                :size => 1..2.megabyte,
                :resize_to => '250x350>',
                :thumbnails => { :thumb => '40x40!' }

validates_as_attachment

```

end
