2. Media

User defined media (images or video), is defined in the entity "Media Files". 

 

 A media file is composed of 4 attributes. 

 The name Just the name shown in the dropdown, when selecting a component type for a page component. 

 The type Is it an image or a video. 

 The content An image or a video, based on the type selected. 

 An alt-text The alt-text added to the HTML, that will be shown if the media fails to load, and will be used by screen readers. 

 A media file also has 2 system attributes. 

 The public path A path to where this file is publicly available. 

 The alt public path Only used for videos. A path where a thumbnail for this video is publicly available. 

 

 Every time a media file is saved, the file is written to disk, and the public path is updated. If the media is a video, then the video is also re-encoded into the defined resolutions and bitrates . This takes a while and therefore the site will be loading for a little while. A thumbnail is also generated, and that path is saved in the field "Alt Path".
