Image optimization

To ensure the proper performance of the page, it is recommended to include thumbnails of images in the src attribute. Then in the data-mdb-img attribute add the path to the image with higher resolution. If the data-mdb-img attribute is omitted, the lightbox will display the same image as in the reduced size.
