image resize ..using attachment_fu

i ve tried this link http://clarkware.com/cgi/blosxom/2007/02/24
for image resize …everything works fine …but image size remains same
for tiny ,small,medium …i cant change the size …
my model is…

has_attachment :content_type => :image,
    :storage => :file_system,
    :min_size => 0,
    :max_size => 1.megabytes,
    :resize_to => '640X480',
    :thumbnails => { :medium => '200X200', :small => '80X80', :tiny =>
'40X40' }
but
image size is stored in database as
for eg:
               small :23458
               tiny : 23458
               medium:23458

pls help..

Do you have image_science and or Rmagik installed? they are
responsible for the image processing (resizing...) also, in windows it
will be much more dificult to make it work.

also try removing the min_size (since it is not used) and putting the
thumbnail sizes in arrays instead of strings

has_attachment :content_type => :image,
    :storage => :file_system,
    :max_size => 1.megabytes,
    :resize_to => '640X480',
    :thumbnails => { :medium =>[200, 200], :small => [80, 80], :tiny
=>
[40, 40] }
