Images in linked files are out of order

I have, perhaps, one last thing keeping me from delivering a 700-page epub:

The images placed in Fm11 are showing up out of order in the converted Rh10 project!

Has anyone seen this, and any thoughts on how to fix it?

NOTE: These (mainly screen captures) images are copied into the document. I saw a reference within the Tech Comm blog to use only graphics imported by reference. If I need to swap them out, what are my options for doing so automatically???
