I debated re adding it, but I felt it was un-needed, as it made the page look slightly cluttered, and there was already an image of Aang (which gave more detail) just above.
If you feel it is needed, you can always re add yourself.
The other image was about Aang and past lives but this image IMO is very important, Korra's bending is being restored and IMO it is the most important image because it's the first time Avatar looses his bending.
