As it says in the comment:

"Run this from an org-buffer after you have exported it to a LaTeX file"

The function assumes that you have already produced a .tex file from
your .org file (e.g. with C-c C-e l l). Then, in your org file buffer
you call it:

    M-x ox-manuscript-remove-image-extensions RET

What the function does is get the filename for the current buffer
(i.e. the name of your org file), derive the name of the produced
tex file, get the contents of the tex file assigned (as a string)
to tex-contents, do a search-and-replace operation on tex-contents
and write the result back into the tex file. The search-and-replace
operation searches for strings that look like this:

          \includegraphics[...]{foo.png}

and replaces each occurrence with

          \includegraphics[...]{foo}
