Hi Michael,

Thank you so much for your accurate instructions about my question.

I think i'll use a custom CommandButton defined as follow, to accomplish what i want to do :
moi\:CommandButton.small_icon > img {
width:6em; (or 64-96px)
height:6em; (or 64-96px)
}

I should like to echo the appreciative words about the way you maintain live and challenging this forum.

Marco.

No problem Marco. 6em will be a pretty large image though. But you can tune that number to whatever size works best for you.
