OK, this is driving me nuts. I really need the functionality for a few  
sites I’m using Radiant for. The only thing I can think of is that the  
ImageScience gem is bad or something. I’ve got RMagick, ImageScience  
and mini\_magick gems installed. Any ideas?

below is a terminal extract:

Mike,

If you want to use ImageScience, you need the FreeImage library  
installed. Notice that it says ‘FreeImage.h: No such file or  
directory’. You can download FreeImage here:

[http://freeimage.sourceforge.net](http://freeimage.sourceforge.net)

Sean

p.s. attachment\_fu, the Rails plugin that is included in  
page\_attachments, prefers ImageScience over MiniMagick and RMagick. If  
you want it to fall back on one of those, you have to either uninstall  
the ImageScience or specify the processor in page\_attachment.rb.
