It would be nice if a published web gallery did not require clicking or sliding in order to view a new picture. Is there a template that just puts up every image in the gallery, full-size, one above another? That's how I like my webpages - see, for example, www.sgrhoa.net/betz/150205/ .
The built-in templates do not do that. At a quick glance, none of the available templates from Adobe's site do that either.
