Making localized version of a skin is pretty easy in jAlbum. First make sure you are using the language: Tools -> Preferences -> Language and if using the latest skin version (http://jalbum.net/skins/).
jAlbum has its own translation tool since version 8.11. Just fire up Tools -> Translator -> Translate selected skin if no translation exists yet, or Update translation otherwise.
While giving support for Turtle skin some of the questions pop up from time to time. I gathered here some of the most frequently asked ones.
I’m aware finding the Settings window isn’t obvious sometimes. You can go to settings either by clicking the “gears icon” below the project on the left hand side or clicking the “skin icon” next to the selected skin or choose the “Album ยป Settings” menu. The skin’s proprietary settings are gathered on the skin tab (called “Turtle” for example).
