Description

Even with the newest image containing Nextcloud 30.0.2 the preview of the photos captured with iOS 18 are missing. Funnily enough there is a message that you should not use Imaginary as it has known issues with HEIC files.

The issue is fixed with an upgraded libheif (1.18.0 includes the needed change) and an ImageMagick version compiled against it.

Research direction

Start by tracing how the Docker image provides ImageMagick and libheif, since the issue names libheif 1.18.0 and an ImageMagick build using it but no files or tests. Done means previews are generated for HEIC photos captured with iOS 18.
