This bug has been confirmed by David Cousens. He wrote: That problem doesn't occur on Linux Mint at all so it may be a Windows exclusive. It works fine on GnuCash 2.6.18 on my wife's Samsung TabPro running WIndows 10. I just updated the Tab Pro to GnuCash v3.2 and as you said the .png graphics in the help file do not show up. Possibly the installer is either not loading the graphics or putting them somewhere Windows 10 doesn't look for them. Over to the developers. David Cousens
This is fixed in git and will be part of the 3.3 GnuCash release.
