zabbix 7 image upload limit

[neorejdv76]

Hi,
I am using zabbix 7.07 with Niginx, postgress, and timescaleDB.
I want to upload an image to zabbix what has got a size of appox. 7Mb.
(administration=>general=>images=> switch from icon to images.

But in the upload process i am getting the error:
Cannot add image: Image size must be less than 1 MB.

I have looked for a solution and found serveral.
They all do not allow me to upload files larger then te 1Mb.

What i have tried sofar:
- set the client_max_body_size 20M in the nginx.conf
- set the value php_value[memory_limit] = 256M in /etc/zabbix/php-fpm.conf and /etc/php/8.2/fpm/php-fpm.conf
- set the value php_value[post_max_size] = 20M in /etc/zabbix/php-fpm.conf and /etc/php/8.2/fpm/php-fpm.conf
- set the valuw php_value[upload_max_filesize] = 20M in /etc/zabbix/php-fpm.conf and /etc/php/8.2/fpm/php-fpm.conf
- restart nginx,php8.2-fpm,zabbx-server services
- restart the whole server

Anyone a tip how to overcome the 1Mb limit in zabbix7?

This was how i resolved mine, open the defines.inc.php file in a text editor.
The file is usually located here: /usr/share/zabbix/ui/include/defines.inc.php
Use nano (or your preferred editor): sudo nano /usr/share/zabbix/ui/include/defines.inc.php
Find the line that defines the image size limit
Press Ctrl + W and search for: ZBX_MAX_IMAGE_SIZE
You’ll see something like this: define('ZBX_MAX_IMAGE_SIZE', ZBX_MEBIBYTE);
Comment it out by adding // at the beginning of the line.

Then add a new line with your desired limit in bytes. For example, for 30MB:
// define('ZBX_MAX_IMAGE_SIZE', ZBX_MEBIBYTE);
define('ZBX_MAX_IMAGE_SIZE', 31457280); // 30MB
Press Ctrl + X, then Y to confirm changes, and Enter to save.

Try uploading your image again
Go back to the Zabbix UI and try uploading the image — it should now accept up to 30MB.

You could try editing the MIN_PHP_UPLOAD_MAX_FILESIZE in the /usr/share/zabbix/ui/include/classes/setup/CFrontendSetup.php

Tried editing the file:
/usr/share/zabbix/include/classes/setup/CFrontendSetup.php

Unfortunately is does not bypasses the upload limit.
