  • Keep e-learning images accessible — all images need descriptive alt text for screen readers
  • Use high-contrast images for educational infographics — content must be legible on all screen sizes
  • Compress images for mobile learners — many students access e-learning on mobile data connections
  • Consistent image style across course materials creates a professional, cohesive learning experience
  • Use real photographs rather than stock images where possible — authenticity improves student engagement
