I have two systems where I need to run tex4ht/make4ht. They are different versions of Ubuntu, I believe 18.04 LTS vs 19.04. I use the most recent version of
make4ht from github, but the version of tex4ht is whatever is available in the apt package manager.
Either way, differing versions of tex4ht (presumably) mean that when compiling
doc.tex with an image
fig.eps, say, the image included in the HTML output is called
doc0x.png on one system (the older one), and
fig.png on the other.
I don't particularly mind about the naming convention here. But I would like it to be consistent, otherwise I will need to write an even worse Makefile than I already have.
So is there a way that I can either go back to the
doc0x.png convention on the newer version, or activate the
fig.png convention on the older one? I've read the tex4ht FAQ but I am none the wiser.
