Uploading an image file
Use the Upload file link in the lower part of the left side menu to upload a file from your computer/storage location. Make sure you are not violating copyrights by this upload (uploading equals potentially sharing with anyone with internet access)! ALWAYS include a proper source reference detailing the location the file came from, who the author was, with working external links etc.
TIP: The Wikimedia Commons is full of media which may safely be used - if your referencing is done properly that is!
Placing an image in a wiki page
Basically, an image is inserted by means of a wiki link, as the image file in the wiki is also a wiki page in itself. However, from the prefix 'Image:' the wiki software understands that instead of a link to this page, its media content should be displayed. A number of optional parameters may be used, the most common ones are in the examples below. Any parameter text not recognized as a standard code will be displayed as 'hovertext' (and as footer text as well in 'thumbs' mode), but only when the unrecognized text is at the end of the parameter string! Other parameters have no particular order, as long as they are separated by '|' (pipes).
Make sure to spell the image link correctly, including the extension which is also case-sensitive!
