The epstool utility (which is part of GSview) converts PostScript files
to EPS format an optionally allows a TIFF preview to be added:

http://www.cs.wisc.edu/~ghost/gsview/index.htm

For example:

% epstool -b -t6p -oplot.eps plot.ps

Note that plot.ps would be created in IDL as a PostScript file in
Portrait orientation, *not* an EPS file.

The TIFF preview added by epstool is displayed onscreen when the
PostScript file is imported into applications such as Powerpoint or
Word. However the PostScript version is rendered when the document is
printed on a PostScript printer.

Cheers,
Liam.
