Images have an important role on any sites and also for a blog. Human brain attracts more towards images than text and it is scientifically proved. So the chances of your content being read by someone will be several times more if you set a featured image for your blog post.

It is found that sometimes the memory of pictures or images on a web page is too large that it takes too much time to load the webpage completely. Thus the visitors feel irritated and just close the site for taking too much time to load. Even the total image size can be more than the rest of the page size.

Slow loading time of a site not only decrease the user experience but it also effects on SEO. Google also take website loading time as a ranking factor. So website speed is also a part of SEO now.
