This error occurs when your library components have one or more large-sized images, or multiple medium-sized images. Currently, XD and Creative Cloud Libraries don't allow you to publish components with heavy images. Adobe is working to address this limitation.

Compress the heavy images within the library components, and publish the library. The error message will list all the components in the library having heavy images. Follow the steps below:
-
Compress the image using Photoshop:
- Right-click the image in the component, and select Edit in Photoshop.
- Compress the image.
Click Edit in Photoshop to open the Photoshop app
