I believe internally they call GetIconRefFromFileInfo() and then pass the iconRef to the new -[NSImage initWithIconRef:] API.

The iconRef you get from GetIconRefFromFileInfo() may not correspond to a specific image file on disk. Besides what Glenn Andreas already mentioned in a previous reply, if the file has a Finder badge, or is an alias, you get a new composited image which doesn't exist anywhere.

I seem to recall that WebKit supports some new syntax for doing in-line images - meaning TIFF data (or whatever) specified inside the <img /> tag - so you may want to investigate that instead.
