About Photoprism photo stacking

[gaozhiguo168]

Hi, nice to meet you all. I recently found a problem when using photoprism. When I uploaded a certain album (4700 photos) to photoprism with my iPhone photosync, I found that only 4100 photos were displayed after indexing. I checked for a long time and recently found that some photos overlapped, that is, two completely unrelated pictures were displayed in one thumbnail. For example, a landscape picture and an indoor picture were displayed on the same photo. I found that this was caused by two identical file names, excluding the possibility of the same time. However, I also found that some files with the same file name but different contents did not appear in the same thumbnail after indexing. Of course, these pictures were not taken at the same time and they all had different contents. I tried to cancel the stacking function in the UI interface and the indexing still did not work. I set PHOTOPRISM_UPLOAD_NSFW: "true" PHOTOPRISM_ORIGINALS_LIMIT: 10000 PHOTOPRISM_HTTP_COMPRESSION: "gzip"
PHOTOPRISM_DATABASE_DRIVER: "mysql" in yml PHOTOPRISM_DATABASE_SERVER: "mariadb:3306" PHOTOPRISM_DATABASE_NAME: "photoprism" PHOTOPRISM_DATABASE_USER: "photoprism" PHOTOPRISM_DATABASE_TLS: "false" PHOTOPRISM_UI_LIMIT: 10000 PHOTOPRISM_GROUP_BY_FILENAME: "false" PHOTOPRISM_THUMB_FILTER: "off" PHOTOPRISM_EXPERIMENTAL: "false" PHOTOPRISM_SKIP_DUPLICATES: "false" PHOTOPRISM_AUTO_STACK: "false" PHOTOPRISM_SKIP_VIDEOS: "false" PHOTOPRISM_SKIP_HIDDEN: "false" PHOTOPRISM_DISABLE_CLASSIFICATION: "true" PHOTOPRISM_DISABLE_FACES: "true" PHOTOPRISM_DISABLE_VECTORS: "true" PHOTOPRISM_LOG_LEVEL: "debug" PHOTOPRISM_DETECT_NSFW: "false" PHOTOPRISM_SEARCH_FILENAMES: "true" PHOTOPRISM_THUMB_SIZE: 1024 PHOTOPRISM_THUMB_UNCACHED: "true"
I restarted docker
rebuilt the database
reindexed but it still didn't work. Have you ever encountered such a situation? How do you deal with it? Because I upload a lot of photos in batches, maybe 20,000 photos in total, I can't take them one by one and rename them.

Thank you for your feedback!

Note that it is not possible to disable stacking of files with the same name as this would break important functionality, most notably support for Apple Live Photos (which consist of a photo and a video file), any other multi-file/hybrid formats like RAW/JPEG, and indexing of metadata from XMP/JSON sidecar files.

Reindexing already indexed files after changing the stacking settings does not unstack currently stacked files, however it will prevent newly added files from being stacked by id, place & time or sequential names.

https://docs.photoprism.app/user-guide/settings/library/#are-files-automatically-unstacked-when-i-change-the-settings.

If the problem in your case is that many of your files do have the exact same name, you can consider configuring PhotoSync to rename files on upload. It offers multiple options for this.

Other reasons for missing files can be found here:

Thank you. I followed your method and chose to rename the picture name when uploading it in PhotoSync. I found that the photos were still incomplete in Photoprism, but the effect is very good and it met my expectations. Thank you!
