Add formatter to render images

This allows to compare old and new image in the preview diff screens.

The image formatter is only used if a diff is requested. If no diff is
requested the plain images are returned. This is important to render
images that are embedded in project documentation, e.g. in Markdown or
Asciidoc files.
