Hello, dev.
With your permission, I have allowed myself to translate your file in your SignPicture mod (tried 1.7.10) (en_US.lang)
So I would like to offer it to you as a further localization for the mod.
Translation attached in the appendix.

Thank you in advance for any answer.
Enjoy the rest of your day.

um, next time learn to check if it's possible at all, because Online Frame Picture (dead) and LittleFrame (life) are not compatible for 1.7.10 🙄
