What are some common pitfalls or issues when using the imagecreatefrompng() function in PHP?

One common issue when using the imagecreatefrompng() function in PHP is that it may not handle transparent PNG images correctly, resulting in a black background instead of transparency. To solve this issue, you can use the imagesavealpha() and imagealphablending() functions to preserve the transparency of the PNG image. 

// Load the PNG image
$pngImage = imagecreatefrompng('image.png');

// Preserve transparency
imagesavealpha($pngImage, true);
imagealphablending($pngImage, false);

// Use the $pngImage resource for further image processing
