I tried this, but it only says "error while loading image.heic". 😢

Browser console logs?

Browser console logs?

Nothing suspicious. :/

[skjnldsv]

I guess it's just nt supported 🤷 ?
Can you open the file in a new tab?

[MorrisJobke]

Also this just uses the plain WebDAV endpoint and not the preview one.

[MorrisJobke]

Actually there was something in the console :/

[skjnldsv]

Works for me and uses preview 🤷

@MorrisJobke does your setup have heic previews properly enabled/configured?

[skjnldsv]

@steiny2k please rebase and add a cypress tests for displaying an heic image.
You can most likely just copy like https://github.com/nextcloud/viewer/blob/master/cypress/integration/image.png.spec.js

@MorrisJobke does your setup have heic previews properly enabled/configured?

No. Do I need that? I just use the default configuration. And then it loads the file via WebDAV.

you have a GET request to webdav?

[MorrisJobke]

you have a GET request to webdav?

Yes, multiple. one to each file of the folder on every slide change. So if there are 3 heic images in a folder and I click on one, then the viewer opens and all files are fetched. On the slideshow change to the next all 3 are fetched again and so on.

Rebased and added the tests 👍
