I'm using sharepoint 2013 for our works teamsite. On the home page I use the web part to display staff photos from a picture library. This has worked in the past fine - updating every 5 seconds. When the page comes up it displays a random photo from the library but it no longer updates the photo after the time period. If navigating away from the page and back again a different photo does display. Settings for the web part are Duration: 5 seconds, Library view - All pictures, display mode - random, Display with: Title and description to right, fixed ht 200, fixed width 300,

I did change which picture library was used sometime back but it worked ok and have reverted to old versions to double check and that no longer works.

I've deleted the web part and recreated. I created a new picture library and copied pictures across in case there was something wrong with the library. I've tried IE, Edge and chrome. Have run out of ideas. Any help would be appreciated.

Well, the feature of Picture Library Slideshow Web Part for automatically doing slideshow based on certain time duration will not be working for your Picture Library until CDN is enabled. Find Reference

So to solve the existing Issue for your app, Please ask your O365 tenant Admin to enable CDN.

Action Plan: Use Powershell commands to enable CDN by following this MS Article

Other problem causing this issue may be CDN policy by MS you need to enable CDN for you picture library. you can execute below script with Powershell

$creds = Get-Credential
Connect-SPOService -Url sitename-admin.sharepoint.com -Credential $creds

Get-SPOTenantCdnEnabled -CdnType Private

Set-SPOTenantCdnEnabled -CdnType Private -Enable $true 
Set-SPOTenantCdnEnabled -CdnType Private 
Add-SPOTenantCdnOrigin -CdnType Private -OriginUrl */libname

    Finally got our IT support to look at the CDN enabling and all now working again and my pictures changing perfectly. For anyone else having this problem as far as I know the office-365/sharepoint steps came down to 1.Connect to SharePoint Online tenant with PowerShell 1.1.Connect-SPOService -Url sitename-admin.sharepoint.com 2.Enable CDN in the tenant for private 2.1.Set-SPOTenantCdnEnabled -CdnType Private -Enable $true 2.2.Set-SPOTenantCdnEnabled -CdnType Private 3.Add CDN origin for picture library 3.1.Set-SPOTenantCdnEnabled -CdnType Private -OriginUrl */libname
