Merge files with images

[zzy0705]

Hi, Thanks for your library!

But I found a bug here:

I have two files, file A is text, and file B has text and image.
if the merge order file B and file A (image file first), then no problem,
but if the merge order is file A and then file B, then after open and edit, when I want to save file, word prompt error: "A file error has occurred. Check your network connections or make sure the
disk is properly inserted and not defective."
