That web page is over quota, but I read it from Google's cache.
It says the cause of images broken in winhlp is often because registry entries
like
    * HKEY_CLASSES_ROOT\.png
    * HKEY_CLASSES_ROOT\pngfile
are missing.  I don't think that's the problem.

The help viewer now crashes instead of showing broken images.
Cleanest way to reproduce is
$ wine start ProntoProEdit\ NG.chm 
Here's the core bit:

0017:Call oleaut32.SysAllocString(001990c8 L"mk:@MSITStore:C:/Program
Files/Philips/ProntoProEdit NG/ProntoProEdit NG.chm::ProntoProEdit.htm")
ret=7e01bba7
0017:Ret  oleaut32.SysAllocString() retval=0019bba4 ret=7e01bba7
0017:Call advapi32.RegOpenKeyW(80000000,0019bba0 L"MIME\\Database\\Content

ret=7e281c76
0017:Ret  advapi32.RegOpenKeyW() retval=00000002 ret=7e281c76

L"\6964\3e76\213c\2d2d\7d7d\6e65\2164\616b\6f64\2d76\3e2d\0a0d\703c\6320\616c\7373\453d\646e\542d\706f\6369\263e\626e\7073\3c3b\702f\0d3e\0d0a\3c0a\622f\646f\3e79\0a0d\0a0d\2f3c\7468\6c6d\0d3e\nt/html"
trace:seh:raise_exception code=c0000005 flags=0 addr=0x7e283fd0 ip=7e283fd0
tid=0017

Oddly, I don't then get a backtrace.  (Is our new crash dialog blocking that?)
