This LaTeX package provides caching of \includegraphics calls,
with several useful effects: Recompilations are much faster
(10x speedup observed). Images can be postprocessed with
ghostscript before inclusion, thus: Automatic downscaling to
specified DPI Automatic JPEG compression with configurable
quality Much smaller files (e.g. 10MB instead of 150MB)! Note:
Due to the one-by-one invocation of pdflatex and ghostscript
for each graphics element, the first compilation is typically
slower than usual. Note: graphicscache needs the \write18 call
(also called shell escape). This is a security risk if you have
untrusted TeX sources. graphicscache supports pdfLaTeX and
LuaLaTeX; XeLaTeX is not supported.
