Are there any specific considerations to keep in mind when working with GIF images compared to other formats in PHP?

When working with GIF images in PHP, one specific consideration to keep in mind is that GIF images support transparency, which may affect how the image is displayed or manipulated. When working with GIF images, make sure to handle transparency properly to avoid unexpected results. 

// Example code snippet to handle transparency in GIF images
$gifImage = imagecreatefromgif('example.gif');

// Enable alpha blending for transparency
imagealphablending($gifImage, true);

// Save or display the modified GIF image
imagegif($gifImage, 'modified.gif');

// Free up memory
imagedestroy($gifImage);
