No idea if you find difficult to choose the right licence to apply to your photographs or content; however, surfing the net found this flowchart that explained, in a simple way, how to choose one. Flowchart needed a bit of love so I vectorized it and publish so everyone can use it. Even if it doesn’t show all licences available it’s a quick tip to choose the one that adapts more to your needs :)

that’s not a bad idea… at some point I remember I had planned to do it in that color, but a cousin walking behind me told me “what is that? looks like Christmas!” so I change it to yellow :$
You could make CC-BY and CC-BY-SA green, as they are truly free licenses as per http://freedomdefined.org/.
Yeap, as I said at the post; there are some missing. Probably later I will do a bigger flowchart with all CC licences so people can have a wider perspective of the selection range :)
Very nice!
However, I think you forgot the Share-Alike clauses in that layer you people want to limit how others remix. ;)
