To do some fancy shmancy insert image here nonsense, try [img] tags, like so:
You need to get the URL of the actual image first (not the imgur URL). Should look like this in the end:
[img]http://i.imgur.com/apUy0c8.png[/img]
Also, save your work without any zoom, please! We have zoom capacities here as well, so it's best to save everything at 100%
