If you use the dark mode plugin, here is some updated code provided by our friendly AI that fixed the inverted pictures. I am still going to tweak this plugin some more to try and clean up the colors of the fonts to make it a more black and white theme. The colors tend to make it look a little busy.

The file you need to edit is located in the Pluginst/darkmode folder and is named: darkmode.php You need to completely replace the code block starting with: /**
* On charge la minification avant
**/
function darkmode_head()
{

Here's the updated code block that will fix the inverted images.

function darkmode_head()
{
    $plugin = 'darkmode';
    # Lecture des données
    $data = flatDB::readEntry('plugin', $plugin);
    $config = flatDB::readEntry('config', 'config');
    $out = '';
    $assets = HTML_PLUGIN_DIR . $plugin . DS . 'assets' . DS;

    if ($data[$plugin . 'state']) {
        $out .= '	' . PHP_EOL;
        // Add custom CSS to prevent image inversion
        $out .= '	' . PHP_EOL;
    }
    return $out;
}

Thanks minim, I just updated the plugin by integrating your css into the minifier file.

After Install the darkmode plugin a big blue arrow appears in the left Side.
But only in dark mode.
How can I repair this?
