Re: [libreoffice-users] Compress images

Hi :)
How about as an add-on/Extension for Draw?

Do we really need more bloat in Writer to make it into yet another
image editor?  I'm happier using dedicated programs and thus making
the images available for use elsewhere and in other programs.  Just
because Word does something bad doesn't mean we have to follow.  Part
of the extra advantage of LibreOffice is that it works on low spec
systems that MS Office can't cope with.
Regards from
Tom :)
