EPS Files Without Preview

[Bruce Pourciau]

In the past, inserting graphics in eps format has worked beautifully  
in LyX, as long as the files were saved with no preview attached to  
them. Eps files with a preview cause an error ("An error occurred  
whilst running epstopdf"), and the pdf compiles with an empty space  
where the figure should be. Someone has scanned in some figures for  
me, cleaned them up (using In Design, I think), and then saved them as  
eps files. They say they have saved them without any preview attached,  
but when I insert them and try to view the document, I get the same  
error I always have gotten when there's a preview.

Any thoughts? Could there be some kind of preview still attached?
