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.
