Yep.  That's correct, apart from the word "links."  They're not really
links.  Not in
the HTML meaning of the word.

You CAN do that, if you want.  But the image tag is a bit of a mess, because
more than one format has been used for the value (URLs and wikimedia
references, as well as others).  So best to use wikimedia_commons=* for
wikimedia commons images.

Sounds sensible.  Actually, I hadn't considered using the category name and
know it worked with any carto that handles File (such as gk.historic.place).

See guidelines on bulk/automated edits.  There are likely to be many
objections, even
if your proposal is sensible and there aren't many to change.

Also seems sensible.  Sorta like what gk.historic.place does on
POIs with images if you click on them for details.  Or, if ever we move to
maps, maybe details would appear in a pop-up if you hover over a POI.  I
this is a good idea, but others may have different opinions.
