This looks great. One minor issue: when I change pictures, a thumbnail of the new picture appears briefly and the text below moves up, before the full size picture loads and everything flicks back into place. (I suspect the timing varies between seconds and too quick to notice, depending on internet speed.) Is there an easy way to fix that? Certes (talk) 23:42, 7 June 2018 (UTC)
