Is it possible to change the size of an image that is uploaded to a wiki page. They all seem to be fixed at a standard size which only covers a small area of the screen. Thank you

Which image size, share the screenshot so community users can understand your issue.

This is a screenshot of the Wiki page, the content of the page seems to be restricted to a small area on the screen. I was just wondering if there was anyway of increasing this area so the image could be larger. Thank you
