What are the potential drawbacks of automatically starting a new line after every 3 images in a gallery system coded in PHP?

One potential drawback of automatically starting a new line after every 3 images in a gallery system coded in PHP is that it may not provide a visually appealing layout if the images have varying heights. To solve this issue, you can use CSS to create a grid layout that automatically adjusts the positioning of the images based on their heights.

php 
// Code snippet to create a grid layout for the gallery
echo '<div class="gallery">';
foreach ($images as $image) {
    echo '<div class="gallery-item">';
    echo '<img src="' . $image['url'] . '" alt="' . $image['alt'] . '">';
    echo '</div>';
}
echo '</div>';
```

CSS code snippet:

```css
.gallery {
    display: grid;
    grid-template-columns: repeat(auto-fill, minmax(200px, 1fr));
    grid-gap: 10px;
}

.gallery-item {
    display: flex;
    justify-content: center;
}
