Plugin H5P – HTML5 Package, is a plugin for e-learning and content management systems that allow the creation of interactive content such as interactive videos, presentations, games, quizzes, etc. H5P is written in JavaScript and allows easy creation, sharing and reuse of HTML5 content and applications that are interactive and accessible. Unfortunately, despite the user side of H5P content being well-developed, information for developing new content is scarce. In this paper the interactive game of the ICT-AAC Competence Network from the University of Zagreb, Faculty of Electrical Engineering and Computing, called e-Gallery, was replicated, which allows browsing, reproducing and editing stories in the gallery. Special focus was on interactivity and accessibility to ensure that the game is tailored to all users. The content of the gallery itself can be easily modified through an interface within the Moodle system that is compatible with the H5P plugin. Each story in the e-Gallery can be easily scrolled through by using the keyboard or through the content itself. It also has the option of playing sound as a story reading. H5P is a relatively new technology that has a lot more to offer, but it still needs a lot of development and creating as much new content as possible.
