Show thumbnails for attached images

After using the new 'attachment feature' I immediately had the wish to show thumbnails for the images attached. :-)

Of course this would be nice for even more file types (eg. PDF and so on) - but I don't know how difficult this would be and I think images are the most useful case.

Maybe WIC would be helpful !?

WIC enables application developers to perform image processing operations on any image format through a single set of common APIs, without requiring prior knowledge of specific image formats.
