Previewing Figures

[Bruce Pourciau]

A LyX file with inserted eps figures prints fine, but only if I print 
directly from LyX. Normally I preview in and print from Preview (on my 
Mac), but running pdflatex on my LyX file gives me this LaTex error 
message: "I could not locate the file with any of these extensions: 
.png, .pdf, .mps, .tif

How do I preview and print from Preview when my LyX file contains eps 
figures?
