I was using Source Editor, so never got to see prompts or anything pop up.
Yep, when using the Source Editor, the only place where something's hopefully going to pop up is your imagination.
Though IIRC the Source Editor does
highlight the syntax it recognizes with different font colors ...
Will that tell me where to upload images and how to properly cite the image's url, or should I continue leaving that alone?
... I have to admit that editing pages
complete with adding new images is something that I prefer the
Visual Editor for. (Or maybe I should say "prefer
red", it's been quite a while.) One reason being that the popups are quite helpful for
that, because you're actually editing
three objects at once (page with text, the file with the actual image, and the description text thereto) while the Source Editor deals with only one at a time; the other being that positioning, resizing etc. an image on a page with text
flowing around makes WYSIWYG worthwhile.
Having that said ... I notice that you cannot display
an image's "info page" anymore unless you're logged in. Nice jump scare, Fandom ...
(Also, the problem of my(?) browser often only displaying the first two or three images on a page extends
beyond the arrows following a link ... WTF?)
Next try: Having that said, the images on the SSSS Wiki tend to not have an actual
description (like a Wikipedia image would, a la "photo of Kastrup's waterfront from due East, taken with a TuuriCam 0815 and ASA Harðardóttir film, at 31-Apr-2012 17:43 local time" yadda yadda). They should have a license / copyright note (so as to cover our legal rears), which will automatically add them to the "LicensedMedia" category for technical purposes, and one thematic category (just so that the per-category listings of pages and images are proper; we don't yet have enough pages and images that we're
forced to work with sublists, though).
Technically, both license and category go into "the description" (text file), like this (copied straight out of the Source Editor):
== Licensing ==
{{Permission}}
[[Category:Characters]]
but the categories are easier to edit with the special clicky-box at the end of the image's info page, rather than starting the full-blown editor.
As you can see, the licenses are, again, ready-to-use templates; "Permission" indicates that we obtained explicit permission from the copyright holder to use the image on the wiki, and covers all of the SSSS comic artwork, as Minna has given us blanket permission in the early days of the wiki. (The templates also contain the magic for the automatic "LicensedMedia" category.)
Every now and then, Fandom updates the cached results for certain "complex" searches, in particular, the
list of images that have not been categorized. Another special search lists the
images without a license note - technically, "images that are
not in the magic 'LicensedMedia' category".
(If someone were to upload an image and add only a copyright notice, these two lists would still fail to notify me of the missing
thematic categorization, but that has not happened so far.)
The single "root" category of the SSSS wiki's tree of categories is "
Browse" (original Wikia default), with the "thematic" categories collected under Browse →
Content →
SSSS, and an extra ... →
Non-SSSS for, e.g., ARtD material.
(Yes, the "tree" displays are unwieldy to navigate. Once you have an idea of the hierarchy, it'll be faster to find / select categories from the
"flat" list ...)
