Export As Image when saving map file

[foozmeat]

I have a folder of small Tiled files that form components of a larger map. I'd like to save an imagerep of these whenever I make a change to the Tiled file. This would give me a gallery of components without having to open them all up and browsing.

I'm on the Mac so I imagine this as a toggle under the File menu to "Export as Image when Saving". The export could use settings stored in prefs or simply use 100% zoom with only visible layers.
