JCRApplication has internal SimpleFileNodeRenderer for output files added to repository. Files are rendered as simple stream. You can add documnets, pdf files, videos, images...

On image files, framework has additional logic for dynamicly resizing images. This is very handful for designs and for efficient managing image resources. You only have one original image and you can get it by any size you need without streching using framework smart resising.

Eg. if we have Desert.jpg image, adding w and h parameters will resize image on the server.

Desert.jpg?w=120&h=80		Desert.jpg?w=20&h=440
Desert.jpg?w=320&h=240
Desert.jpg?w=520&h=180
