You can use unoconv[0] (a universal office converter that works with
anything that LibreOffice or OpenOffice support) to convert them to a
pdf file. Then use ImageMagick[1] to convert them to png files.

Here is a quick script (that probably doesn't work so don't blame me if
it fails) on how I would start doing it:

Hope this helps.
