There's several wikis:
1. Image are hosted on the common wiki [1], then
2. added in a English (or French, German...) wiki pages (URL en.wiki.ryzom.com or fr.wiki.ryzom.com or de.wiki.ryzom.com). You can add a single image in the text (img) or use the gallery (nice for explanations, better is the text is quite long, easier for the author to manage).
Once the 1st image is imported (and is ok), paste '''in a simple notepad''' the codes you will use on Common (when you upload your file, such the '''Category'''), as usually, we use the same type of categories, under a title Images on COMMON WIKI. It's useful to have codes under ENGLISH Wiki, with the categories used on the english wiki, and some frequent code.
On the top menu: Tools/Upload file.
For ex, if the image is a big screenshot, with text in German, and in a perfect world :p
