hi.

I use attachement\_fu and create this two thubnails of an image.  
:thumbnails =\> {  
:medium =\> ‘380x\>’,  
:thumb =\> ‘x100\>’  
}

Is it possible to replace the existing :thumb image with another image?  
The main Image and the :medium should remain unchanged.

thanks  
michael

Hi Michael,

Just wondering if you found the answer to this question – I’m trying to  
figure it out myself.

Thanks!
