[Tex/LaTex] \includegraphics: Dots in filename


\includegraphics cannot handle filenames that contain more than the one dot, separating the filename from the extension. Apparently it uses everything after the first dot as extension and then, of course, complains about an unknown graphics extension.

This is annoying as I very often have filenames that contain parameter values, e.g. plot_a0.4_b0.6.pdf.

Is there a way to teach LaTeX to interpret only the string behind the last dot as extension?
