Lightbox not showing correctly in responsive mode

Joomla 5.1.1
Hot Transport template
When you visit this page: joomla-support.co.nz/index.php/our-renta...bins/king-size-cabin
The lightbox module and image layout look fine in desk top mode. Although images push out beyond the right side of module.

When you visit the same page in responsive mode images look poor quality.
Also show as large as opposed to scaled for smaller screen width.
Also the full gallery image list is not available for viewing.

Thanks in advance for your assistance.

Hello,

You should reduce the width of the module. Currently, it's set to 500px.

The thumbnail images are set to 200px. That's the quality you can expect on both desktops and mobiles. If you are using images that are poor quality, the automatically created thumbnails will also be poor quality. Also, you can increase the quality of the thumbnails in the module settings. You must re-create the thumbnails after changing this parameter. This can be done if you delete the old thumbnails.

Regards,
Milos
