Petr Macha developed and stabilized Question Image Support for the scrumdojo/quizmaster repository, enabling quiz questions to display images triggered by specific emojis. Using React with JavaScript and TypeScript, he implemented logic for emoji detection, image URL assignment, and robust rendering within the quiz interface. Over six iterative commits, Petr focused on UI integration, formatting improvements, and edge-case handling to ensure consistent user experience and minimize broken-question scenarios. His work enhanced quiz engagement by allowing visual content in questions, addressing both feature implementation and stability. The depth of his contribution reflects careful attention to front end development and user interaction.
