Convert .bimg to tiff, png or jpg


I am currently running Microstation Connect Edition Update 16, with its associated visualisation.

I do have a substantial amount of legacy .bimg files (previous luxology history files) that were created with a previous version of Microstation Luxology.

I can preview these files in Windows explorer, I presume through  a Microstation plugin, but I cannot open these file in Microstation.

How do i convert these files to a common image format like tiff, png or jpg?

Any help appreciated,

Regards, Marcel Tossings
