What I'd like to have is. When I get a GIF image it has a default size
which
looks very nice on screen.
When I create a screenshot and save it as GIF and later show it in a
HTML
document it appears very butifully.
Even when I print a HTML document containing a GIF the result is
perfect.
I used GIMP to convert GIFs to EPS and/or PS but the result was always
ugly. I
tried ImageMagics with the same result.
After all I gave up.
For me it is completely unimportant what is the image format, I want
perfect
result.
I do not understand why EPS and PS image formats are used at all by
LyX/LaTeX,
they are very big (I mean in size)
there are no tools to convert the now standard GIF, JPEG, PNG images to
these
obsolete formats.

With pdflatex I managed to create a kind of slide show document (A5
landscape)
presented in Acrobat Reader full-screen mode.
Pdflatex has also problems with images. It also is not be able to
calculate the
default size.
Until there is no a tool to create acceptable EPS or PS images, the only
solution is to use HTML.
I'd be one of the happies man if I found LyX/LaTeX solution to my image
problems.

Anyway, excuse me if my previous posting appeared on the list, this was
a
technical fault of me.
