and dont forget to add height and width to the attr_accessible list and fix
this
height = dimensions.height
width = dimensions.width
to
self.height = dimensions.height
self.width = dimensions.width
also you can remove the style from
has_attached_file :photo, :styles => {
:original => ["100%", :jpg] ,
}
to
has_attached_file :photo
and you have an extra comma that does not goes there
at the end it should look similar to this
has_attached_file :image,
:url => "/system/assets/images/:id/:style/:basename.:extension",
:path =>
":rails_root/public/system/assets/images/:id/:style/:basename.:extension"
validates_attachment_presence :image
validates_attachment_size :image, :less_than=> 800.kilobytes
validates_attachment_content_type :image, :content_type => %r{image/.*}
the red charactesr means you should but the size you want there, you can
remove
validates_attachment_size :image, :less_than=> 800.kilobytes
if you dont want to set a limit.

my replies have many typos , some time i write 'user' instead of 'used'
and 'is' instead of 'if'
you may want to check that in case something is not clear
