@Mustafa-Kaddoura, please update the existing path: # sphinx_gallery_thumbnail_path = '/_static/axial_fan_performance_curve/problem_schematic.png' with # sphinx_gallery_thumbnail_path = '_static/axial_fan_performance_curve/problem_schematic.png'. The leading slash is the issue. Also please make sure the file exists.
