The file also exists on Commons. There, there are links for four different resolutions of the image; [[ https://upload.wikimedia.org/wikipedia/fa/thumb/2/2a/Imamzadeh_abbas.jpg/223px-Imamzadeh_abbas.jpg | 223 × 240 pixels]], [[https://upload.wikimedia.org/wikipedia/fa/thumb/2/2a/Imamzadeh_abbas.jpg/445px-Imamzadeh_abbas.jpg| 445 × 480 pixels]] and [[https://upload.wikimedia.org/wikipedia/fa/thumb/2/2a/Imamzadeh_abbas.jpg/557px-Imamzadeh_abbas.jpg | 557 × 600 pixels ]] are rendered okay, but [[ https://upload.wikimedia.org/wikipedia/fa/2/2a/Imamzadeh_abbas.jpg | 800 × 862 pixels ]] is rendered sideways. I also tried some other resolutions and 500px and 501px are rendered sideways.
