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.
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) and RU (Russian).

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). You can create your own category, to collect your lucios, on Common (see for ex (https://atys.wiki.ryzom.com/wiki/Category:Lou_Tei-Sang%27s_herbarium Lou Tei-Sang's herbarium]).

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), under Encyclopatys/DE/Gameplay 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).
