About how :

find an image in Commons, using categories (or in a tab or in list) ;
choose categories for your images .

Defaut language for Ryzom Commons wiki is English (Common URL start with atys.wiki.ryzom.com), it has all the files for the other wikis (the llwiki.ryzom.com with ll=en, fr, de, ru or es).

It means that all wiki's tags are in English (category, template...).
It means too that the categories tree is not the same (that the forge or en.wiki or de.wiki... localized wikis) as it's on common name spaces.
If you post image will a lots of French/Spanish/German text... thanks to add in the Summary a language tag, as EN (English), FR (French), DE (German), SP (Panish) or/and RU (Russian).
translators can find information about how to translate a common category ^[1], and most of us need them because it's not easy to choose the good keyword :)

An image must be at least in a category under [[Category:images]] but can use several categories (they should have, a text to illustrate image, and 2 or 3 categories ^[2]. You can create your own category, to collect your lucios, on Common (see for ex ^[3], then it's cool to add in it links to wikis related pages and manage the album collected in the common category.

As Categories are not easy to rename, better take 1 mn to think about their names (and organization).
On the page of a category, the images are sorted by name. Also, if you want them to be displayed in a certain order, you must name them first.

Heernis translated

(a long document, from Arily, 2008) in German.

As most images have lot of German, Heernis created a sub-category (named Ruinen von Silan - Beginner Guide), later we add it under EncyclopDE witch is under Encyclopatys, to host images (in case someone don't like PDF).
the PDF file is under Category:Comics and under Silan Anleitung (help images with many German text).
