In this study, the authors envision a solution for online editors with accessibility considerations for images. To do this, an architectural metamodel with three levels is proposed: environment, guidelines and information system components. A set of 20 requirements was identified. This set was used to assess the accessibility level of a sample of 12 online platforms. The sample included different types of online platforms: massive open online courses, learning management systems, content management systems and social networking services. After analyzing the results, the authors found that in terms of management of images, the most accessible platforms were Moodle, Sakai, ATutor and MiriadaX. In addition, an insert/edit image interface with accessibility features was prototyped. The validation of this interface showed compliance with the Authoring Tool Accessibility Guidelines (ATAG) 2.0 and the HTML code generated complied with the Web Content Accessibility Guidelines (WCAG) 2.1.
