There are several pre-existing PHP gallery scripts such as Coppermine, Piwigo, and Gallery that can be easily customized for specific needs. These scripts often come with a wide range of features and options that can be tailored to fit the requirements of a particular project. By utilizing these scripts, developers can save time and effort in building a custom gallery from scratch. One potential solution is to use the Coppermine gallery script and customize it according to your specific needs. Here is an example of how you can modify the layout of the gallery using CSS:

// Custom CSS for modifying the layout of Coppermine gallery
echo '<style>
        .imageblock {
            width: 200px;
            height: 200px;
            margin: 10px;
            float: left;
            border: 1px solid #ccc;
        }
        .imageblock img {
            max-width: 100%;
            max-height: 100%;
        }
      </style>';
