Images not displaying in line with text

[OliverB21]

I am using markdown for my posts, and when I insert an image it doesn't sit in the centre or match the width of the post. When previewing the markdown, the images sit in line with the text. The MD I am using is below:

![The Blast Premier Spring Final stage, from the back of the arena](https://oliverb21.github.io/blog/img/posts/09_old_seats.jpg)

The result can be seen on this page:

TIA :)

fixed by using HTML tag instead of MD
