What are potential pitfalls when using different image types (GIF, JPG, PNG) in PHP image manipulation functions?

One potential pitfall when using different image types in PHP image manipulation functions is that the functions may not support all image types. To solve this issue, you can use conditional statements to check the image type before processing it with the appropriate function. 

$image_path = 'image.jpg';

$image_info = getimagesize($image_path);
$image_type = $image_info[2];

if ($image_type == IMAGETYPE_JPEG) {
    $image = imagecreatefromjpeg($image_path);
} elseif ($image_type == IMAGETYPE_PNG) {
    $image = imagecreatefrompng($image_path);
} elseif ($image_type == IMAGETYPE_GIF) {
    $image = imagecreatefromgif($image_path);
} else {
    die('Unsupported image type');
}

// Perform image manipulation functions here

// Output or save the manipulated image
