What Size Should I Make Images for the CorpU Player
If your goal is to use the full content space, 1080px wide is the target size. Adding images over 1080px wide will be scaled to 1080px to optimize the image for the maximum size inside the course player. Uploading an image over this size may result in grainy or fuzzy images. You can add other size images under 1080px as well and have them show to your users in their full, responsive display.
