Graphics won't convert

[TJ]

Hey,

Ive been searching around the web for an answer to this problem and  
can find nothing. I am running a Mac with the latest version of OS X  
and I have followed the installation page that I found on one of the  
Lyx.org linked sites. My question is when I put a jpg or any other  
graphic in the document and then try to view it in any of the output  
views I get the error "No Information for converting jpg format files  
to eps. Define a converter in the preferences." I understand that I  
need a converter to do this but how do I add one? Which one do I use?  
Another item of frustration for me is that when I try and run the  
view=>DVI command it does nothing. Any help would be great.

Thanks,

TJ
