Many social networks, websites and messaging applications allow users to upload a wide variety of media files, and although the majority of files are in the form of images and video clips, a significant minority are audio files. When the website or application subsequently needs to display a thumbnail that describes the uploaded content, images can be cropped and resized down to scale, and a single frame from a video clip can be converted to an image and then also cropped and resized down to scale.
As a website/app developer or owner, you’ve undoubtedly experienced your fair share of glitches and mishaps when it comes to users or site visitors sharing your content. Many outlets such as news and media sites, social networks, or e-commerce sites include the option to "like" or "share" content such as blog posts or images. Once shared, the social network site displays a snippet of the shared content alongside a featured image. This way, your site content gets maximum exposure in social networks and attracts additional visitors.
