pdflatex/xelatex/lualatex can handle eps images just fine.
You can first run ps2eps on the ps files.
E.g. I can take knot3.ps - one of the files, (which is not bitmap, but
a proper postscript) run
ps2pdf knot3.ps
producing knot3.eps, move knot3.ps out of the way, and then
\documentclass{article}
\usepackage{graphics}
\begin{document}
\includegraphics{knot3}
\end{document}
works just fine.
Or, perhaps, you prefer xelatex, then you'd need
\usepackage[xetex]{graphics}
Dutto for lualatex, you'd use
\usepackage[luatex]{graphics}
IMHO one should not use pdflatex, which is obsolete, but switch to
lualatex or xelatex.
