Hi all,

I use attachment fu for image upload. In my model I define 3 thumbs.  
The orginal image is resized but the thumbnails are not. People have  
reported this issue before but I have not seen a solution yet.

I have this issue both on Windows and Linux.

Someonehas a solution for this?  
thanks  
Stijn

class Image \< ActiveRecord::Base  
belongs\_to :album  
has\_attachment :content\_type =\> :image,  
:storage =\> :file\_system,  
:max\_size =\> 500.kilobytes,  
:resize\_to =\> ‘384x256\>’,  
:thumbnails =\> {  
:large =\> ‘96x96\>’,  
:medium =\> ‘64x64\>’,  
:small =\> ‘48x48\>’  
}

validates\_as\_attachment  
end
