Hi
Welcome to Microsoft community.
I understand that you are experiencing the missing images issue. Here are some steps you can take to troubleshoot:
Clear Browser Cache: Sometimes, the browser cache can cause issues with displaying content. Try clearing your browser's cache and cookies then restart your browser.
Disclaimer: Your browser automatically saves temporary internet files to help pages load faster. Clearing this cache will sometimes fix website issues. Please back up all your personal files first, such as Favorites, to ensure you do not lose data.
Try a Different Browser or Device: If possible, try accessing your saved images from a different browser or device to see if the issue persists.
Check Your Internet Connection: Make sure you have a stable internet connection as this could affect loading of images.
Update Your Browser: Ensure that you're using the latest version of Google Chrome as outdated versions can sometimes cause problems with websites.
As for syncing Bing collections to OneDrive, unfortunately, there is no direct way to do this. Bing collections and OneDrive are separate services and don't have built-in integration for syncing at this time.
However, you could manually download images from your Bing collections and then upload them to OneDrive as a workaround.
Please feel free to let me know if you have any further updates, thanks.
