What are some common mistakes beginners make when using imagecopy() in PHP for image manipulation?

One common mistake beginners make when using imagecopy() in PHP for image manipulation is not properly specifying the destination image resource. To solve this issue, make sure to create a new image resource using imagecreatetruecolor() and use it as the destination image in the imagecopy() function. 

// Create a new image resource for the destination image
$dest = imagecreatetruecolor($width, $height);

// Copy the source image onto the destination image
imagecopy($dest, $src, $dest_x, $dest_y, $src_x, $src_y, $src_width, $src_height);

// Output or save the manipulated image
imagejpeg($dest, 'output.jpg');

// Free up memory by destroying the image resources
imagedestroy($src);
imagedestroy($dest);
