Documentation:
Rules characterizing image files that can be inlined into LaTeX.

A rule consists in an association whose key is the type of link
to consider, and value is a regexp that will be matched against
link's path.

Note that, by default, the image extension *actually* allowed
depend on the way the LaTeX file is processed. When used with
pdflatex, pdf, jpg and png images are OK. When processing
through dvi to Postscript, only ps and eps are allowed. The
default we use here encompasses both.

You can customize this variable.

This variable was introduced, or its default value was changed, in version 24.4 of Emacs.
