Category: VIP File System

Responsive images are automatically supported by WordPress core. Image markup will automatically include srcset and sizes attributes for images uploaded to a WordPress site’s Media Library. These attributes enable web browsers to automatically use and display the most suitable image size based on a device’s screen size.

By default, a set of alternate sizes are generated for images that are uploaded to a site’s WordPress media library. These alternate sizes are referred to as “intermediate images”. WordPress core defines a default array of intermediate image sizes: thumbnail, medium, medium_large, and large. The pixel dimensions for each of these default sizes can be defined in the Settings –> Media screen of the WordPress Admin dashboard.

Default behavior of image files (e.g., jpg, png, gif) that are located in a site’s /uploads/ directory, served by the VIP File System:

The system temp directory (/tmp) is a local, writeable path on an application’s web servers on the VIP Platform. The /tmp directory is most commonly used to perform local manipulations to temporary files. For example, transferring a ZIP archive to /tmp, extracting its contents, then uploading the contents to the WordPress site’s wp-content/uploads/ directory on the VIP File System.

On most platforms, media files uploaded to a WordPress site are stored in a filesystem local to the site’s web server. On the VIP Platform, media files uploaded or imported to a WordPress environment are stored on the VIP File System, which is an external object store. A WordPress site’s /wp-content/uploads/ directory is mapped to this external object store. This design provides better security and allows VIP’s CDN to more easily scale access to a site’s media.
