Attachment_Fu ImageScience and FreeImage problems

I have been trying to run the UploadImages Recipe from Mike C.'s
Advanced Rails Recipes book. I have installed both ImageScience and
FreeImage on my Ubuntu 7.10 box. When I run the program and try to
upload an image, I get a strange error which appears as follows:

ActionController::RoutingError (No route matches
“/images/blank-cover-small.png” with {:method=>:get}):

Note that I am really trying to get Insoshi up and running and I get
exactly the same error so I am pretty sure that the problem is in my
installation of ImageScience and FreeImage but I do not know how to
troubleshoot it.

Any help would be greatly appreciated.

Thanks.

I have managed to get around this problem by installing ImageMagick and
RMagick combination. So not an attachment_fu problem afterall. Does
anyone have decent installation instructions for ImageScience and
FreeImage on Ubuntu 7.10?
I installed FreeImage from source and am not sure what went wrong where.
