EPS figures in Textures (&LaTeX) once more

I am writing a paper using LaTeX and the Textures program in
Macintosh. I have problems with including EPS figures. This is a topic
that has been discussed A LOT but reading and trying out all kinds of
things made me confused especially bacause nothing sees to work. I
want to know what is the truth. Are EPS files (from Adobe Photoshop
Elements) not good for Latex at all as some websites suggest? Or is
there a simpler way or another postscript format that suits better?

Originally I used bitmap files and the \special command in Textures
and this worked fine but the picture files are huge and I need to be
able to convert my tex code to other LaTeX systems than just Textures.
Then I have tried the following 2 approaches:
(1) \usepackage{graphicx}.... ...
\includegraphics[width=3in]{mypicture.eps}

(2) \input BoxedEPS
    \SetTexturesEPSFSpecial... ...\BoxedEPSF{mypicture.eps scaled 200}

(3) \special{postscriptfile mypicture.eps scaled 200} 

Of these (1) is commonly used in LaTeX I think, and (2) is recommneded
for Textures. In each case the code goes through Textures without
errors. I have these packages included with my Textures. In (2) the
space that is left blank in the Textures typeset window suggests that
the shapes of the figures are taken into account and that the
EPS-figures were found.

I "print" my manuscript first to a postscript file and look at it in
Ghostview and then make a pdf file (my Textures lacks the automatic
pdf converter). This has worked fine without the figures and with the
bitmap figures. But these EPS files simply do not go through to the
final postscript output file - or at least do not show in Ghostview
(ps file created using the print (File menu) command by checking the
"print to file")! Any simple remedies?

Unfortunately I cannot print the ps file to a postscript printer. I
also tried all formats jpg, tif, png, pdf for the figures... no
success.
