The upload works fine and the images are copied from the temporary directory into an uploads directory in the merb root with the original filename. now i want to create thumbnails using RMagick, but when I add the code, I get an internal server error when i try to load page: Internal server error 500 uninitialized constant Photos::Photo You can view my model, controller and views at here: http://pastie.caboo.se/160545 Thank you for your help Flo -- Posted via http://www.ruby-forum.com/.
