Questions & Answers about Quiero guardar la imagen en una carpeta nueva.
Spanish often drops subject pronouns because the verb ending already tells you who the subject is.
- Quiero = I want
- So yo is not necessary
You could say Yo quiero guardar la imagen..., but that usually adds emphasis, contrast, or clarification:
- Yo quiero guardar la imagen, no borrarla.
= I want to save the image, not delete it.
Without yo, the sentence sounds natural and normal.
