  This study explores spherically symmetric non-linear electrodynamics black
holes and their effects on light propagation. We derive the governing metric,
revealing radial coordinate dynamics within the event horizon. We analyze
photon trajectories, finding that increasing magnetic charge expands the
horizon and emission range. Furthermore, with the help of the Event Horizon
Telescope results, we constrain parameters and emission profiles. Direct
emission dominates, while lensing rings play a lesser role. Comparing with
Schwarzschild black holes, we observe higher intensity but a wider emission
region in non-linear electrodynamics black holes. This work enhances our
understanding of modified spacetimes and their impact on black hole properties.
