Thank you for your report.

Is that correct, that you don't have files preview on your instance?

[filipdot]

when i send it works, when somebody then not. Sometimes it works some times it doesn't. My message: Somebody else:

[Antreesy]

When you send it, we use blob with local picture to not load it again from server (until restarted) Unless it's an actual desktop issue, same should happen in browser (own upload previews available, others - not)

i get 404 in browser when trying to generate preview

Correct, we get this also. Works in mobile talk but not on desktop talk.

Hi; I have same error, in Windows and Linux Desktop APP, in Android APP and in the Web Browser client direct on Nextcloud interface. Im searching for solution in web and / or awaiting for Nextcloud team for one solution.

[frmoronari]

Hi again;

For problem in Talk in browser, i have one solution. Edit nextcloud config file "config.php", generally in "/web-server-root-directory/nextcloud/config/config.php" and adding these lines on end file:

array (
    'OC\Preview\PNG',
    'OC\Preview\JPEG',
    'OC\Preview\GIF',
    'OC\Preview\BMP',
    'OC\Preview\XBitmap',
    'OC\Preview\MP3',
    'OC\Preview\TXT',
    'OC\Preview\MarkDown',
    'OC\Preview\OpenDocument',
    'OC\Preview\Krita',
    'OC\Preview\HEIC',
  ),

before last ");" in file.

I'm still search for solutions for other platforms (Windows and Linux App and Android APP).

[frmoronari]

Hi again again;

One update, the solution above resolve all platforms.

This print is the Talk in Linux:

Red is before config, Green is after config.

After edit file, i´m reload web server (apache2) in my server.

We also had this problem, no pictures in the desktop app but it worked fine in the mobile app and in browser.

Turns out the only problem was the setting 'enable_previews' in config.php. Changed this from false to 'enable_previews' => true, and the pictures started working right away. I have no idea why this was turned off, it's an older instance that got updated over the years. Maybe there was a time when the default setting was false or someone turned off previews for performance reasons.

Maybe there should be a configuration warning if previews are turned off and Talk is enabled.

Hi @tim-geier ; Could you please tell me in which configuration block you made the change?

Because my "config.php" doesn't even have this option (enable_previews) inserted. Thanks

[Antreesy]

my "config.php" doesn't even have this option (enable_previews) inserted.

Then it's true by default: https://docs.nextcloud.com/server/latest/admin_manual/configuration_server/config_sample_php_parameters.html#enable-previews

BTW: The button to CLOSE the preview is shown ONLX on 'mouse-over' so you can fid it only 'by accident'. That's annoying, especialle as you can't exit preview with 'escape' either.
