    <p>Image crop. You can pass the parameters in the url to get your desired output image size like this <code>image.php?src=img/random.jpg&amp;w=300&amp;h=200</code></p> <pre><code>&lt;?php header("Content-type: image/jpeg"); $image = imagecreatefromjpeg($_GET['src']); $thumb_width = $_GET['w']; $thumb_height = $_GET['h']; $width = imagesx($image); $height = imagesy($image); $original_aspect = $width / $height; $thumb_aspect = $thumb_width / $thumb_height; if($original_aspect &gt;= $thumb_aspect) { // If image is wider than thumbnail (in aspect ratio sense) $new_height = $thumb_height; $new_width = $width / ($height / $thumb_height); } else { // If the thumbnail is wider than the image $new_width = $thumb_width; $new_height = $height / ($width / $thumb_width); } $thumb = imagecreatetruecolor($thumb_width, $thumb_height); // Resize and crop imagecopyresampled($thumb, $image, 0 - ($new_width - $thumb_width) / 2, // Center the image horizontally 0 - ($new_height - $thumb_height) / 2, // Center the image vertically 0, 0, $new_width, $new_height, $width, $height); imagejpeg($thumb); ?&gt; </code></pre> <p>In terms of putting one image on the page at a time and browse through them use previous and next button. That would require some javascript to achieve that. </p> <p>There are many nice gallery that would display the image one at a time, and they already take care of the image resize issue.

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
