It is XPM image data in a different module than the one I fixed and committed yesterday.  This time it's in the fmresources module which is imported from labelbook.

I would like to keep the typo fixes you did in this module, just with the 'INB_..." items reverted back to what they were before.  Since you already appear to be interested in this module I thought you might be able to fix the image data that it needs too.  But if you do not want to then I can add it to my todo list, but I don't know when I will get around to it.
