Is it possible to access the properties of an image when it's been loaded in to
an swf?

I am thinking of the properties which can be edited and displayed in the
Windows directory listing.

The image 'contents' field could then be used as the caption for the image
viewed in flash.

Native Flash loadMovie and MovieClipLoader only can give you image file bytes and height and width of container_MC. It does not provide file metadata.
