hi Giovanni
i am interested
du you mean that if i copy paste this code in my-init, then when inserting an
image, the width by default, instead of being 1par may be what i want, say
5cm width ?
that would be very very convenient
would it work for each type of inserted image (copypasted image, linked
image…)
