Revamp filename item in PictureViewer2

Turn it into something completely different :)
Display filename, scaled size, file size, added date and mime type in
the upper left corner of the viewport.
Make it more visible. A pinkish background doesn't always work esp. with
a gradient background. Make it white with 80% alpha channel with a black
foreground.
