This study explores how visual images can trigger social action for difficult causes by examining the "Woman, Life, Freedom" movement in Iran, catalyzed by the tragic death of Mahsa Amini. Two emotionally charged visuals—Mahsa on a hospital bed and her grieving parents embracing—became symbols of this movement, uniting activists and global supporters across cultural and geographical boundaries. The research draws on the concept of emotion-symbolic work, emphasizing how visuals evoke emotions that inspire collective action. These images, shared by courageous journalists on social media, demonstrate the power of grassroots visuals in fostering solidarity and challenging systemic injustices. Using a case study approach, the analysis integrates semi-structured interviews with key activists and content analysis of social media and public commentary. The findings reveal how visuals elicit profound emotional reactions, such as sadness, anger, and compassion, inspiring actions like protests, online campaigns, and creative expressions. Furthermore, the study highlights the transformative process by which certain images become global symbols, representing broader systemic issues and mobilizing communities for sustained action. This research contributes to social movement literature by illustrating the interplay between visual imagery, emotional resonance, and collective action. It also provides practical insights for social entrepreneurs and movements addressing global challenges like climate change and sustainability. By leveraging the emotional and symbolic power of visuals, social actors can effectively inspire meaningful change and reshape societal norms on a larger scale.
