JPG photos larger than 9 MB are not displayed

[jtinov]

Hello Team,

i reduced the size of a photo in a test series in incremental steps. Everything was fine below 9 MB. If this limit is intentional, it would be too low for most photos taken on smartphones and other devices.

Best regards

The problem is thumbnails service. It is pain in the ass.

Add this to .env

THUMBNAILS_MAX_INPUT_WIDTH=90000
THUMBNAILS_MAX_INPUT_HEIGHT=90000
THUMBNAILS_MAX_INPUT_IMAGE_FILE_SIZE=50000000
PROXY_AUTOPROVISION_ACCOUNTS=false

and ths to yml

yml
thumbnails:
  thumbnail:
    transfer_secret: sIDz+a^2C#*Z@R7DVAFF08VFKYBA4imZ
    webdav_allow_insecure: true
    cs3_allow_insecure: true
  service_account:
    service_account_id: 0cd841de-a582-4977-ade8-8ae7f87db2bc
    service_account_secret: zOhrpMl-6-CY-efUoPy#SZ4OA5GSYl*z

I did that, and it magically started working.

Why? The limitation is intentional and can be changed by the config.

THUMBNAILS_MAX_INPUT_WIDTH=90000
THUMBNAILS_MAX_INPUT_HEIGHT=90000
THUMBNAILS_MAX_INPUT_IMAGE_FILE_SIZE=50000000

The technology behind the thumbnails service is libvips, which performs quite well https://github.com/libvips/libvips/wiki/Speed-and-memory-use

You always have to limit stuff, but the config can be changed.

Many thanks, yes, that’s exactly it.
The parameters were actually already mentioned in the documentation: https://docs.opencloud.eu/de/docs/dev/server/services/thumbnails/environment-variables#environment-variables-for-the-thumbnails-service
I hadn’t realised that a missing thumbnail prevents the photo from being displayed.
