Hi We are trying to put a watermark in our rental portal for the  
property pictures uploaded by users; how do you do it with file\_column.  
I searched but could not find anything.

thanks

This isn’t a Ruby question; it’s a Rails question. However, one can  
add watermarks to images with RMagick. I suggest asking how to use  
RMagick with file\_column on the Rails list.
