Sorry for the long delay; I didn’t get notified of this question.
Yes, this does work with custom post types as well. I’ve just updated the plugin JavaScript code as well for higher compatibility.
Thank you @wolfpaw
Late but safe! 🙂
I like this plugin and I’d like to help translate it to spanish.
The translator tool gives the warning the plugin is not ready for translation or not properly.
Do you think it is possible? I don’t have much experience making plugins but I hae translating, so let me know!
Thanks for the offer @marbaque! I realized that I never added translation files, and I cleaned up the code a bit and made it more translatable today. I’d greatly appreciate the translation.
If you do take the time to translate it, note that I made the URLs translatable too, since the Creative Commons licenses are also in multiple languages at different URLs.
Very well @wolfpaw I’ll work on the translation to Spanish.
