How to add Images to MediaWiki
You can add images to your MediaWiki Pages to make them look better. This can be done by uploading the desired image in your MediaWiki folder. Then you need to indicate it in your post as an image using : [[image:tst.png]] (where tst.png is the name of the image).
You can also add
thumb nailed images using: [[Image: tst.png |thumb|caption]]
The images can be aligned so that you can add text next to it. Here is an example how to create a left
aligned image:
[[image:tst.png|left|thumb|50px|]]
