There have been many researches about having images on web pages. Pages with images are more likely to be shared on social media. Users choose articles which contain images and get 94% more total views than articles without images. Pages that have at least one image perform better in organic search than pages without images.
The advantages of having images are evident, however, if they are not well-optimized, they may add several megabytes to your page load sizes and be extremely detrimental to your sites performance. Decreased site performance may lower your search engine rankings and provide a frustrating experience for users.
