image

To include an image on its own line (i.e., a block image), use the image:: prefix in front of the file name and square brackets after it.
image::sunset.jpg[]
If you want to specify alt text, include it inside the square brackets:
image::sunset.jpg[Sunset] // you can also give the size into square brackts: image::sunset.jpg[Sunset,300,200] // an images with an URL and size given: image::https://upload.wikimedia.org/wikipedia/commons/3/35/Tux.svg[Tux,250,350]
If you want to include an image inline, use the image: prefix instead (notice there is only one colon):
Click image:icons/play.png[Play, title="Play"] to get the party started. Click image:icons/pause.png[title="Pause"] when you need a break.
