Image path uses 'workday-wql' directory, but all other images in this file use 'workday-raas' directory. This inconsistency will likely result in a broken image reference. The path should be '/images/workday-raas/image5.png' or a unique filename to avoid conflicts with the existing image5.png on line 151.

Image path uses 'workday-wql' directory, but all other images in this file use 'workday-raas' directory. This inconsistency will likely result in a broken image reference. Additionally, line 165 already uses 'image6.png' for a different section. Consider using '/images/workday-raas/' directory with unique filenames like 'image7.png' and 'image8.png'.
