Hello Ben,

You can Follow the implementation of an image gallery component in the original request you opened for it: https://feedback.telerik.com/blazor/1442530-image-gallery. It also offers a couple of pointers on implementing it right now - it's easy to add our tooltips or a window with load-on-demand for details or the larger image, and various effects are usually a few lines of CSS3 nowadays that you can add through classes on the images.

For example, the page you linked uses a simple span behind the images with a few settings like this:

    background-image: url(the-same-img-url);
    filter: blur(14px);
    top: -14px;
    left: -14px;
    transform: scale(0.95);

Regards,
Marin Bratanov
