Hi,
What is it an image of?
Also, not sure what you mean by "survive the various translation software." I would note that all localization vendors should be able to handle PNG, JPEG, TIFF, in addition to AI and PSD, if not CDR (certainly, if they can handle your FM files, they can handle all of these graphics formats). Additionally, translation to another language should not alter a raster image -- I am curious about your translation workflow.
Thanks,
Sean
