Possibly another dumb question...

I found a copy of Objectworks Smalltalk and the archive consists of 2 2.88 diskette images (.diskimage extension) that show up in windows explorer as 2881k. When I try to mount them in the Previous Floppy screen, it complains that they are of an invalid size and says they must be 720k 1440k or 2880k.

Is there a way to use these in Previous?

Thanks in advance.

You need to strip the 46 byte header from the diskimage file, see this thread from 2021 (http://www.nextcomputers.org/forums/index.php?topic=4581.0), e.g. using the dd command on Unix (if/of specify the input and output file, respectively):

dd ibs=1 skip=46 obs=512 if=1.img of=1_skip_start.img

Gotcha. Didn't find that thread in my apparently feeble search. Appreciate!
