What potential issues or limitations should be considered when working with GIF images in PHP?

One potential issue when working with GIF images in PHP is the limitation of the GD library, which may not fully support all features of the GIF format. To address this, consider using a more robust image processing library like Imagick, which provides better support for GIF images.

// Example code using Imagick to work with GIF images
$image = new Imagick('image.gif');
$image->resizeImage(200, 200, Imagick::FILTER_LANCZOS, 1);
$image->writeImage('resized_image.gif');
$image->destroy();
