I am copywriting for an app that also includes French as a language. According to official writing guidelines, grammar may be wrong for the sake of brevity, e.g. instead of saying "Would you like to save the changes?" one may ask "Save changes?" Now, in French there is a tendency for sentences to become very long. e.g. "Select profile picture" would become "Sélectionner une image de la profil" As I am not a native speaker of French, I am unsure in which ways shortening of French sentences is acceptable for the sake of title brevity. Would it, for example, be acceptable to write "Sélectionner image profil"? What are common phrasings for titles in French?
