This example displays three groups of static images on a single HTML page, each group headed by a title (“Group 1,” “Group 2,” “Group 3”) and containing a row of thumbnail-like images. It uses plain HTML and CSS with flexbox (via `display: flex` and `flex-wrap: wrap`) to arrange the images responsively, and each image is defined with an `<img>` tag referencing a local file such as `image1.jpg` or `image5.jpg`. The code relies on a simple DOM structure without any JavaScript libraries or data-binding frameworks, making it a minimal, non-interactive layout for organizing image collections.
