I don't know whether you are using TeX Live or MiKTeX, but TeX Live

sam2p filename.jpg filename.eps

certainly does what you need.  It creates much smaller files than
ImageMagick and is significantly faster.  I don't know whether sam2p
is provided by MiKTeX.

However, since PostScript and PDF understand JPEG, programs like
ImageMagick, sam2p,... don't actually convert JPEGs, they just put
wrappers around them which provide additional information needed by PS
or PDF processors.  Hence, if the EPS files can't be included in
LaTeX, it's possible that your JPEG is broken.

If in doubt, simply send me your JPEG file and I can investigate
myself.

Regarding pdf[la]tex, yes, it can include JPEG files directly.  It
just creates the wrapper itself.  Technically, there is no difference
whether you include a JPEG directly or "convert" it to PDF before and
include the PDF.  But dvips can't do that itself and relies on

exact error message.  If external programs are involved, such as
JPEG->EPS converters, it's also helpful to know which TeX distribution
you are using.

And please don't rely too much on TeXnicCenter.  It's easier to do
things step-by-step on the command line first and configure
TeXnicCenter later.  If you configure TeXnicCenter, you have to know
how the programs havew to be invoked on the command line anyway.
Do the first step first, it's easier in this way. :)

Reinhard

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
