Hi @larafif and welcome to the community!
You are right that an extra step is needed if wanting to use media (such as logos/images) in multiple-language forms.
Here’s the info from the support site: Adding Various Types of Media (image, audio, video) to a Form — KoboToolbox documentation
And an example from another user: Image display problem in the second language - #7 by Kal_Lam
All the best with your form!
