Images & video

Images and video bring your articles to life. C3NTR makes it easy to add a cover image, insert photos within the body, and embed video from YouTube, Vimeo, or your device.

Cover image

Every article can have a cover image that appears at the top. It sets the tone before the reader sees a single word.

To add or change a cover image:

Focal point editor

After choosing an image, a focal point editor appears. Pinch to zoom, drag to reposition, and choose a crop ratio. Fixed ratios like 16:9 and 4:3 are available, or you can use freeform crop for full control.

The focal point is saved with the article, so the image always looks right on different screen sizes.

Inline images

You can insert images within the article body using the toolbar image button or the /image slash command. These appear inline between paragraphs, right where your readers will see them.

Video

Articles can include a header video that plays inline. C3NTR supports three sources:

• YouTube URL — Paste a link from YouTube.
• Vimeo URL — Paste a link from Vimeo.
• Upload from device — Record or choose a video from your camera roll.

The video picker has tabs for Recent, URL, and Upload, making it quick to find what you need.

Media Library

Your school has a shared Media Library where all uploaded images and videos live. You can find it in Settings > Media Library.

From here you can:

• Browse all uploaded images and videos.
• See your storage usage and how much quota remains.
• Delete individual files to free up space.
• Use the Recents tab to quickly find recently used images.

Storage

Images and videos count toward your school's storage quota. The quota depends on your plan tier. You can check your usage at any time in Settings > Storage & Cache.

Unsplash

C3NTR includes built-in Unsplash search, giving you access to a large library of free, high-quality photographs. When you use an Unsplash image, attribution is handled automatically.
