A really simple theme as seen on my blog
Requires an extra property in your _config.yaml
file
author :
gravatar :
url : https://en.gravatar.com/userimage/13363990/4bd44ba6339e4525ad9f839f46244100.jpg
caption : Looking snazzy...
If you don't want to use a Gravatar for the avatar image, just go to _includes/themes/zen/default.html
and set your own image url there.
Another thing to note: the bio text which sits underneath the image is just hardcoded html in the _includes/themes/zen/default.html
file - handle this as you wish (I couldn't be bothered implementing a cleaner solution for this, but including another file with a bio is not a difficult task if you wish to do so)
Enjoy!
