I maintain a very basic cheatsheet (https://github.com/trufa/git-cheatsheet) if anyone is interested, I think it is a little bit more helpful since it links to relevant explanations and has some clarifications beside the code.
I did it for myself (because I kept forgetting) so it's not very thorough, but still a little more helpful if you ask me, it will get better with time and/or collaboration (unlike an image!).
Note that the very basics are not included, those you tend to remember them soon enough IMO.
If you're interested it's hosted on github and I would be very happy if anyone want's to collaborate:
