--- Comment #5 from Benny <jf...@web.de> --- I just made some additional testing: I set up a QNAP with a 2.5 Gbps connection and tried my sample pictures on the QNAP with an SMB 3.0 Share on the QNAP (180-220 MB/s throuput over 2.5 Gbps connection). Opened DigiKam on Windows 11 and added my sample pictures on the QNAP as a new collection on network shares. It took 50 to 60 seconds too to open a not-preloaded HEIC-image in the preview window inside of DigiKam 8.7.0 Build Date 09.06.2025 13:02 (LibHEIF 1.19.5). I still hope you could add a workaround for this behaviour. Here you can download my sample HEIC photos: https://www.jff2k.de/upload/files/2025/test_heic.zip -- You are receiving this mail because: You are watching all bug changes.
