I have a Photo model (below) and as you can see I create some  
thumbnails. However I want to create a proportionally thymbnail, which  
basically will be a cropped version, so that the thumbnail will be a  
perfect square.  
I use attachment\_fu and ImageScience to handle photo uploads. Can  
anyone help me or give me a hint on how to create my cropped  
thumbnails ?

class Photo \< ActiveRecord::Base

belongs\_to :user

has\_attachment :content\_type =\> :image,  
:storage =\> :file\_system,  
:size =\> 1.byte…12.megabytes,  
:thumbnails =\> { :thumb =\> ‘125x83\>’ , :MS =\>  
‘500x333\>’ },  
:path\_prefix =\> “/public/photos/”

validates\_as\_attachment

end

Thanks,  
Demetris.
