Give me a lightweight protection script that blocks casual right-click/image saving while keeping text selection and SEO intact

es. For your website, I recommend not blocking text selection. The following lightweight script only discourages casual right-clicking and image dragging/saving, while normal text remains selectable and crawlable.

Add this near the bottom of your page, before </body>:

<script>
(function () {
    'use strict';

    // Disable right-click only
    document.addEventListener('contextmenu', function (e) {
        e.preventDefault();
    });

    // Prevent dragging images
    document.addEventListener('dragstart', function (e) {
        if (e.target.tagName === 'IMG') {
            e.preventDefault();
        }
    });

    // Prevent common image-related mouse actions
    document.addEventListener('mousedown', function (e) {
        if (e.target.tagName === 'IMG' && e.button === 1) {
            e.preventDefault();
        }
    });

    // Prevent opening images with middle mouse button
    document.addEventListener('auxclick', function (e) {
        if (e.target.tagName === 'IMG') {
            e.preventDefault();
        }
    });

})();
</script>

Optional CSS for images

You can also add:

<style>
img {
    -webkit-user-drag: none;
    user-drag: none;
}
</style>

What this does

Feature	Result
Normal text selection	✅ Allowed
Copy text	✅ Allowed
Google crawling	✅ Unaffected
SEO text/content	✅ Unaffected
Right-click	🚫 Disabled
Drag image to desktop	🚫 Discouraged
Middle-click image	🚫 Blocked
JavaScript disabled	Protection disappears
Screenshots	❌ Cannot be prevented

Important

This is only casual protection, not real content security. Anyone can still use browser developer tools, disable JavaScript, take screenshots, or retrieve images from the page source/network requests.

For an SEO/content website, this is preferable to code such as:

document.onselectstart = () => false;
document.oncopy = () => false;
document.onkeydown = ...

because those approaches interfere with legitimate users and accessibility without providing meaningful protection.
