If you’ve lost your sound and images, but had obtained them from a shared deck, if the shared deck is still available you can import it into a new profile, and then copy the sounds and images from it into your original collection to restore the data.
WARNING: This is an unofficial duplicate upload of Image Occlusion Enhanced (Image Occlusion Enhanced - AnkiWeb). Please be wary of listings like this as they are not under the control of the original author and could be updated with malicious code in the future. Just like the warning above says: “As add-ons are programs downloaded from the internet, they are potentially malicious. You should only download add-ons you trust.”
You might need to remake some cards, use only the official image occlusion add-on
My problem is unfortunately something else because my screenshots do appear in my anki. The pictures I can’t see are pictures in decks I did not make. Before doing the upgrade, I could see the exact same pictures. This is the reason why I think the problem is the upgrade.
