We are struggling to open IMG files located on old tapes, and DX Files
IMG - The headers state they are DECImage Application Services - this seems to be a binary in IMG031 folder on a binaries CD of a VMS release.
@m_thompson - any ideas?
The DX Files are apparently OpenDX but I’m struggling with this as well- asking about this too
I found this Compaq software description for DECimage editor that ran under DOS or Windows. That program will save DECimage files as TIFF or JPEG. I have not found a copy of this program though.
I found special DEC terminals to display DECimage files, and VMS and Ultrix software to work with DECimage files.
Al Kossow from the Computer History Museum said that there is DECimage software on the dec 1993 consolidated VMS distribution cd. Google found this description of the CD: https://www.avitech.com.au/mm-files/vms-csd-nov92/docs/vms-csd-nov92-users-guide-ocr.pdf
AL Kossow put the complete CD set that contains the DECimage software on bitsavers.

Will work on this on the weekend, I am trying to get an emulator going on my Mac so I can try some of this stuff outside of the ACMS. Thanks to @coolcoder613 this may become a reality sooner rather than later I can hope!!
Another page I may end up using is this for DDIF Files
