Avif images not shown in email

It looks like .avif-type images are not being shown in my emails (it displays the “broken image” icon instead), though .png images (from the same sender) do show up.

They are remote images in both cases. Just in case it makes a difference, the avif images are loaded from cdn.prod.website-files.com and the png images from cosmicimg-prod.services.web.outlook.com

My Mail → Privacy setting is set to “Display unsafe constent in all messages”.

I’m using eM Client 9.2.2307. Any ideas?

em client is up to version 10.1.4588. I don’t know if it’ll help but try Menu > Check for updates and see if the current version can handle the .avif file type.

I can’t update to a higher version as my license is for eM Client 9.

Seeing as I can’t update past eM Client 9, will someone please confirm if eM Client 9/10 can load avif images?
