Media
Upload and organize your images and files, and understand how images are resized.
The media library holds every image and file you use on your site. You upload something once and can then use it on as many pages as you like.
Start here
Media library covers the basics of getting files in and keeping them tidy. Read that first, then the other two as you need them.
Everything in this section
- Media library: uploading files, using folders, and moving, renaming or deleting what you have.
- Images on your site: how BrightSite resizes and crops each image to fit where it is used, and what to do when something important is cut off.
- Image best practices: the habits that keep your site fast and your library usable, such as large originals, descriptive file names, and alt text.
You do not need to resize first
Upload the largest version you have. BrightSite makes the smaller sizes for you and serves each visitor one that suits their screen. Images on your site explains what happens to your original.
