(Tomos at Wikipedia wiki_tomos@hotmail.com): As I understand, there are two ways to use an image from another language-wikipedia... Is one way more recommended than the other?
Images should not be shared among Wikipedias. it is our goal to have each Wikipedia be complete and self-contained, except for links to the Internet at large. Disk space is cheap--if the same image appears in 10 wikis, then it should be uploaded 10 times and linked locally in each. That way, when we make a backup of each wiki, each backup contains the whole content.
