Images under which of the free licenses can I use in a template intended for sale?

Question

Licenses for software and other works

I want to try to create a template for wordpress for sale.
The question arises: images under which of the free licenses can I use in a template intended for sale?

Answer 1

IANAL.
You can use the works under any of the free licenses for your own selfish purposes. That's why they are free . However, the use of some of them can be quite cumbersome in this case.
Examples of free licenses: CC0 and other public domain release formulas , WTFPL , BSD three -clause license , CC-BY , CC-BY-SA , GNU GPL , GNU FDL .
I have listed them here in ascending order. GNU FDL- this is a license for books, it requires that the work has source code in addition to the binary form, and obliges to distribute its full text along with the work - in short, it is not suitable for images; nevertheless, there are quite a few pictures under it, because until 2008 it was a license from Wikipedia and related projects. GNU GPL is a license primarily for software, considerations for applicability to images are the same; however, several icon packs are distributed through it and, as Google tells me, a number of these WordPress templates of yours; so you can meet her too.
These two plus CC-BY-SA are copyleft licenses(English copyleft), they require that the work, a derivative of the protected by them, should also be free on terms no more restrictive. If, according to a shaky but generally accepted opinion, a copyleft illustration to the text does not extend its copyleft to the text, design and other illustrations, because they are quite independent from each other; then the design element on the design as a whole - most likely yes.
At first glance, this is not a big problem, because you, as a highly moral person, will sell your work as free anyway, right? But there is a compatibility issue here.licenses - you want to borrow some from work under one copyleft license, say the GNU GPL, and some from under another, say CC-BY-SA; both require that the final work be on the same conditions - how to be? That's right, no way - it's simply impossible to combine other people's work under the GNU GPL and CC-BY-SA within your own.
As for non-free licenses, they are well known, for example, CC-BY-NC and CC-BY-ND, CC-BY-NC-SA and CC-BY-NC-ND, but in general there are hundreds of them, because write a non-free license for your work you don't need a lot of brains.
