== Undocumented: muted and loop options for videos; others? ==

[[File:Mengerzugendlossequenz 2880p60 20200226 color CRF04.webm|thumb|loop|A <code>loop</code> video]]
[[File:Cat piano with audio 3EB0CD1F.webm|thumb|muted|A <code>muted</code> video]]
[https://gerrit.wikimedia.org/r/c/mediawiki/services/parsoid/+/816208/1 A couple of years ago], the <code>loop</code> and <code>muted</code> keywords were added to codebase. Examples to the right.

These are not documented. Which makes me wonder, if there are other important undocumented options...

Should I go ahead and add these to the page?

== How to ''link'' to a specific DjVu/PDF page? ==

The {{para|page}} parameter allows selecting a specific page in a DjVu/PDF file when ''displaying'' an image (example: <code><nowiki>[[File:Alice in Wonderland.djvu|thumb|page=5|Page 5 from ...]]</nowiki></code>). However, this does not work for ''linking'' to a specific page:
* <code><nowiki>[[:File:Alice in Wonderland.djvu|page=5|p.&amp;nbsp;5]]</nowiki></code> gives "[[:File:Alice in Wonderland.djvu|page=5|p.&nbsp;5]]" with a wrong text and a link to the whole file instead of its specific page.
* <code><nowiki>[[:File:Alice in Wonderland.djvu?page=5|p.&amp;nbsp;5]]</nowiki></code> gives "[[:File:Alice in Wonderland.djvu?page=5|p.&nbsp;5]]" with correct text but a wrong link with [[percent-encoding|percent-encoded]] <code>?</code> symbol.
Is there a valid wiki syntax or a helper template to achieve this without using an "external link" (<code><nowiki>[https://en.wikipedia.org/wiki/File:Alice_in_Wonderland.djvu?page=5 p.&amp;nbsp;5]</nowiki></code>)? — [[User:Mikhail Ryazanov|Mikhail Ryazanov]] ([[User talk:Mikhail Ryazanov|talk]]) 21:50, 17 March 2025 (UTC)
: Found the template myself (accidentally): {{tlx|PDF page link|file{{=}}Alice in Wonderland.djvu|page{{=}}5|text{{=}}p.&amp;nbsp;5}} gives "{{PDF page link|file=Alice in Wonderland.djvu|page=5|text=p.&nbsp;5}}". No wiki syntax apparently exists. — [[User:Mikhail Ryazanov|Mikhail Ryazanov]] ([[User talk:Mikhail Ryazanov|talk]]) 02:52, 24 March 2025 (UTC)

== Specifying image dimensions for OpenGraph metadata ==

The article on [[Kat Abughazaleh]] has an image, [[commons:File:Kat_Abughazaleh_2_(portrait_cropped).jpg|a portrait photo of the subject]] that a contributor cropped from [[commons:File:Kat_Abughazaleh_2.jpg|a larger photo]], in the infobox. When social media sites extract metadata from that page via OpenGraph and prefer a landscape-oriented image ([https://bsky.app/profile/spm1961.bsky.social/post/3lolwbe7qbc2m example]), the default dimensions/crop are sometimes pretty suboptimal, displaying the person's nose and mouth but truncating the eyes.

Off the top of my head, I can imagine a few ways of fixing this:

# Include two images on the page; use <code>class=pageimage</code> and <code>class=notpageimage</code> to override the [[mediawikiwiki:Extension:PageImages|Page Images]] selection criteria so that one goes into the social media preview and the other is actually displayed to those who visit the page
# <nowiki>replace the current image with the prior uncropped image, use {{</nowiki>[[Template:CSS image crop|CSS image crop]]<nowiki>}} or {{</nowiki>[[Template:Annotated image|Annotated image]]<nowiki>}} to crop it appropriately for portrait display in the infobox, so that the re-cropping by OpenGraph has more to work with</nowiki>

I welcome advice! [[User:Sumanah|Sumana Harihareswara]] 15:24, 13 May 2025 (UTC)

== Centre a caption? ==

Is there a way to centre align (or centre justify) a caption below an image? [[User:Spideog|Spideog]] ([[User talk:Spideog|talk]]) 14:48, 5 June 2025 (UTC)
