I'm currently writing an article where I need to insert images into the article. I don't know how most of you do it, but I want to know it myself. Can you help me?

It tells you on the right of editing an article how to do it.

Go to the bottom of the page where it says bottom image, then upload your image. If it's the first image you upload, it'll be 'img1'. If you upload a 2nd image, it becomes 'img2' etc.

Type in (img1 center, large) but use the square brackets like ] [ in the space where you are typing out your article, like the example in the pic:

Then press preview to see if you've done it right.
