I am mainly active on the Afrikaans wikipedia, but also contribute to commons in the following ways:
Moving images from language specific editions of wikipedia to the commons.
Moving eligible images from flickr to commons - these generally relate to Afrikaans articles that I work on. This includes asking flickr users to relicence there work with an appropriate license. See for example 2007 Rugby Wêreldbeker
Uploading out of copyright images of South African and Afrikaans topics.
Posting my own photo's of South African topics - let me know if I need to photograph something in Gauteng.
