Hey, thanks banaandigitaal for asking and Steven for answering this question. I never thought to ask, but -- as I mentioned in a recent thread -- I hardly ever add captions. But I use the image numbering, so this perfect for me.
I also now, in the Pro options area, just changed showInfoButton=TRUE to showInfoButton=FALSE. With that caption area color bar now gone, I find I don't have a need to have the "i" nav button present; before, all it did was remove that bar, the image numbering, and my home-page (back) icon (which I have in the upper left). This has the added benefit, to me, of making that navigation bar smaller (narrower), which sometime overlayed some very wide images; this change reduces that likelihood.
Now to revise a bunch of galleries...
Thanks,
Bill P.
