Further to comment #1 I downloaded a file from Google Photos which was in .heic
format
and the file was immediately viewable in Gwenview 23.08.5 (Kubuntu 24.04).
So I'm closing this bug report as 'Fix Released'.
** Tags added: jammy
** Changed in: gwenview (Ubuntu)
Status: New => Fix
Reported here in Gwenview as this is the place where a user notices the
problem ("gwenview doesn't display photos from my iPhone"), but the
underlying problem is that package kimageformats is compiled without
libheif support, see Bug #1951278. It is purely a packaging problem so
please fix it for
