Default path for images

Hello,
I am editing a page and I want to add images using html tag to be able to control the size

<Img src = "/default_path/image3.jpg" alt = "jj" style = "width: 200px;" />

But I do not know what the default image path is.

Default path is the page folder

For controlling size you can use markdown too

You also might want to give the image linking documentation a read...
