Attachment\_fu is making an assumption that image will always be  
uploaded. This is causing problem in my application where the field is  
optional. Does anyone know how to make the image upload optional  
without blowing up the app?

Is there any other plugin that does not make such an assumption? TIA.

I haven’t tried attachment\_fu, but the file\_column plugin lets you  
specify (or omit) validates\_presence\_of just like you would with any  
other attribute.
