Hello Harsh Jain, thanks for posting this in the community.
Since there is no error message, the issue is likely related to temporary app permissions, network connection, or cached data. Please try signing out of your Microsoft account, force close OneNote, reopen it, and sign in again. Also make sure your iPad has a stable internet connection because the Online Pictures feature depends on Bing search to load images. If the problem continues, feel free to update us so we can check further.
Kind regards,
John Oli
