Help:Funtoo Editing Guidelines/Images
To upload images, head to Special:Upload and upload a file. Make sure that all images you upload have the same dimensions. When you upload, make note of the Destination Filename field -- this is the name that the upload will use when you reference it in your slide. It is recommended that you choose a simple descriptive name ending in ".jpg" or ".png" for the Destination Filename.
This section should be expanded to include information on how to insert images into wiki pages. Should also cover embedding video.
