That looks excellent.
How long until this commit appears in the downloadable snapshots? For
some reason, the Apache Subversion server doesn't work through our Squid
proxy, always gives an HTTP 400 error.
You should be able to find it in the latest one from

I've been digging through Excel to try and find where it hides the
image. I can't see the binary as-is in any of the OLE streams. The
only stream big enough to hide the image would be the "Workbook" itself,
and there aren't any records in the workbook large enough to be storing
a 4kB image. The only conclusion I can come up with is that it's stored
right at the end and not inside a record of any sort.
Have you tried comparing the output from poifs.dev.POIFSViewer to
hslf.dev.BiffViewer, so see if there is in fact extra data at the end?
