TYPO3 Core

• Have at least one extra language
• Upload image in filelist
• Fill the metadata
• Translate the metadata of this image
• Make a content element of type "image" in default language
• Make reference to this image in the content element
• Translate the content of this page
• Show translated page in frontend

• The image is not there, the translated metadata is shown
• The img tag is using 0 (zero) for both width and height

Reason:
The column type of width and height are not declared in sys_file_metadata
When declaring the type input for these fields, probably with a readOnly => true, the image is shown again, because the contents of the width and height column are transferred to the translation using l10n_mode = exclude

When adding the following to Configuration/TCA/Overrides/sys_file_metadata.php in my own extension it works

$GLOBALS['TCA']['sys_file_metadata'] = array_replace_recursive(
    $GLOBALS['TCA']['sys_file_metadata'],
    [
        'columns' => [
            'width' => [
                'config' => [
                    'type' => 'input',
                    'readOnly' => true
                ]
            ],
            'height' => [
                'config' => [
                    'type' => 'input',
                    'readOnly' => true
                ]
            ],
        ]
    ]
);
