On your wiki... Example: If your image is to large (like the one in my example) or you just want to change its size, you will need to add some stuff back to the end of the URL. For example, if you want it to be 10px wide: A full list of resizing option can be found here.
 * 1) Upload the image you want to use
 * 2) Go to that image's file page
 * 3) Click the link that says "Full resolution"
 * 4) Go to your browser's address bar and copy the URL. It should look something like "https://vignette.wikia.nocookie.net/central/images/3/3b/Spidey_wiki_v2.jpg/revision/latest?cb=20180628222735".
 * 5) Go to the page "MediaWiki:Common.css" and enter edit mode
 * 6) Place the following at the bottom of the page using the URL you copied from your browser's address bar. I suggest removing everything after the file extension.
