how to connect to a CDN-enabled Image Library

Question

how to connect to a CDN-enabled Image Library to activate the slideshow

Answer 1

To connect to a CDN-enabled Image Library for activating the slideshow in SharePoint, your SharePoint Online tenant administrator must first enable the Content Delivery Network (CDN) within your Microsoft 365 tenancy. Once the CDN capability is configured, you can work with your administrator to enable a private CDN for the Image Library you want to use as the source for your autorotating web part. This involves running additional scripts for the source image library.

For detailed guidelines and instructions on how to enable the CDN and create a private CDN, refer to the documentation on Microsoft 365 Content Delivery Network (CDN) with SharePoint Online.

Answer 2

Dear @Luis Cabrera,

Thank you for posting your question in the Microsoft Q&A forum.

To use the CDN together with the Picture Library Slideshow web part, your SharePoint Online tenant administrator must enable the CDN within your Microsoft 365 tenancy. For reference: Non-CDN-enabled SharePoint Picture Library Slideshow web part no longer switches automatically to new images

To activate the slideshow, the following needs to be completed by a SharePoint tenant administrator:

Step 1: Enable the Microsoft 365 CDN at the tenant level.

Step 2: Register the specific Image (Picture) Library as a CDN origin. See Using your CDN assets to learn about accessing your CDN assets from both public and private origins.

Step 3: Use that CDN‑enabled image library as the source for the Picture Library Slideshow web part.

After CDN capability is configured, you can work with your tenant administrator to enable a private CDN for the Image Library that you want to use as the source for your autorotating web part. To do this, the administrator must run additional scripts for the source image library.

For guidelines and instructions about how to enable the CDN and create a private CDN, see:

• Microsoft 365 Content Delivery Network (CDN) with SharePoint Online.
• Use the Office 365 Content Delivery Network (CDN) with SharePoint Online
• Office 365 Content Delivery Network (CDN) Quickstart

Note: If you do not have access to tenant‑level settings, I recommend contacting your SharePoint or Microsoft 365 administrator and asking them to support you

Alternatively, if you are using modern SharePoint pages, you may consider using the Image Gallery web part (Carousel layout), which provides slideshow behavior without requiring CDN configuration.

For more information, please refer to:

• Use the Image Gallery web part

I hope the information shared helps point you in the right direction. Please try the steps above and let me know if they work. If not, we can continue working together to narrow this down.

The first response may not always resolve the issue right away, but with your help and more details, we can work toward a solution.

Thank you for your patience and understanding. I'm looking forward for your reply.
