Hi. I hope that you can point me to where the configuration exists ...
On a page like https://en.m.wikisource.org/w/index.php?title=The_Works_of_Lord_Byron_(ed._Coleridge,_Prothero)/Poetry/Volume_1 the mobile skin is left aligning images that have been typeset to be centred to align with the remainder of the text on the page, see standard view, s:The Works of Lord Byron (ed. Coleridge, Prothero)/Poetry/Volume 1
So in the end we have people using text centering styles rather than image placement formatting to achieve their ends. Is this image positioning forcing something that we can control at a local level? Thanks.
