What are some common challenges faced by beginners in creating a PHP image gallery?

One common challenge faced by beginners in creating a PHP image gallery is handling image uploads and resizing them to fit the gallery layout. To solve this, you can use PHP's GD library to resize images to a specific width and height before displaying them in the gallery. 

// Example code to resize an image using PHP GD library
$source_image = "path/to/source/image.jpg";
$destination_image = "path/to/destination/image.jpg";

list($width, $height) = getimagesize($source_image);
$new_width = 200; // Desired width for the resized image
$new_height = ($height / $width) * $new_width;

$thumb = imagecreatetruecolor($new_width, $new_height);
$source = imagecreatefromjpeg($source_image);

imagecopyresampled($thumb, $source, 0, 0, 0, 0, $new_width, $new_height, $width, $height);

imagejpeg($thumb, $destination_image, 80); // Save the resized image as a JPEG file
imagedestroy($thumb);
imagedestroy($source);
