Cannot convert postscript images which are included in the LaTeX file 

     It is likely that the macros you are using for including postscript
files (e.g. epsffile) are not understood by LaTeX2HTML
     . To avoid this problem enclose them in an environment which will be
passed to LaTeX anyway e.g. 

     \begin{figure}
     \epsffile{<postscript file name>}
     \end{figure}

     Another reason why this might happen is that your shell environment
variable TEXINPUTS is undefined. This is not always
     fatal but if you have problems you can use full pathnames for
included postscript files (even when the postscript files are in
     the same directory as the LaTeX source file). Alternatively try
setting TEXINPUTS to ".::". With some TeX and LaTeX
     installations setting TEXINPUTS to ".::" may cause problems in the
normal operation of LaTeX. If you get errors such as
     LaTeX complaining that it can no longer find any style files then you
must set TEXINPUTS to "<path to your LaTeX
     installation>:." if you want to use both LaTeX and LaTeX2HTML.
