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] }
