Does anyone know if it’s possible to set constraints to the size & type  
of file that file\_column will accept?

I’d like to limit to image files of less than 2MB.

If this isn’t possible with file\_column, is there a graceful way of  
getting the controller to handle it?

thanks

I’ll look harder next time.

thanks again
