Session variable from a module is only accessible from the template after refresh

Question

To add some common ground. I need to transfer 3 variables from a module to my template when the sites loading. In my module I get 3 links to specific images and they need to be included in the template. So I tried to do in my module:

$session = Factory::getSession();
$session->set('image1', $value);

and in my index.php:

$session = Factory::getSession();
$variable = $session->get('image1');

The issue is that this only works if I refresh my page. I understand that the template is loaded first and the module is loaded second so the template reads the variable before it is set. The question is: Is there away around this? How can I accomplish what I want to?

For this exact issue the solution was to avoid the things that are not working. So instead of trying to get the variable from the module to the template in my php I created a html variable "--myvar" as a placeholder in my template and used:

echo ":root { --myvar: {$variableITriedToGetAcross}; }";

and that proved to be effective because now it works fine but I had to compromise in some way. The thing is the css is loaded after all the modules and templates so the template gets the value trough the css after loading.
