How can PHP developers troubleshoot and fix image distortion or transparency problems that occur when using functions like imagecreatefrompng()?

Image distortion or transparency problems when using functions like imagecreatefrompng() can often be caused by incorrect handling of alpha channels in PNG images. To fix this issue, developers can use the imagesavealpha() function to ensure that alpha channel information is preserved when working with PNG images. 

// Load the PNG image with transparency support
$image = imagecreatefrompng('image.png');

// Enable alpha channel support
imagesavealpha($image, true);

// Output the image with correct transparency
header('Content-Type: image/png');
imagepng($image);

// Free up memory
imagedestroy($image);
