You could just imagine how bare-looking and dull a website is when the textual content of the site is not accompanied by any image or picture as a representation of the text content. This, I believe shall never be as attractive as the websites that contain pictorial representation of what is being narrated.
The use of the embedded images on the website is plainly not because you would like to enhance the aesthetic side of it, but rather, the use of the image creates an ambience that allows the readers to significantly understand and appreciate better what the textual content is all about. This line of thinking was absorbed by generally of the content management systems developers. They view that the incorporation of multimedia on a website not only impacts the aesthetics of the site but more relevantly, it creates a newer method to allow for better understanding to transpire and an effective way to educate web users.
The Drupal software has the image module whose primary function is to permit its users to upload and embed images and pictures on the Drupal-made website. The ability of the image module to create variety of image forms (like in thumbnail and actual image size) made it realistically useful. Best of it, these image sizes are automatically being generated once the image has been permitted to be uploaded on the website. This is a feature of Drupal that has remained unmatched to this date. Now, the latest revisions of Drupal are capable of switching the image size into their own preference which makes it a more preferred feature.
