What potential issues can arise when working with PHP scripts that involve image manipulation and text insertion?

One potential issue that can arise when working with PHP scripts involving image manipulation and text insertion is the possibility of text overlapping or not being displayed correctly on the image. To solve this issue, you can use the imagettftext function in PHP to ensure proper text placement and alignment on the image. 

// Create a new image with specified dimensions
$image = imagecreate(400, 200);

// Set the background color of the image
$bg_color = imagecolorallocate($image, 255, 255, 255);

// Set the text color
$text_color = imagecolorallocate($image, 0, 0, 0);

// Set the font file and size
$font = 'arial.ttf';
$font_size = 20;

// Set the text to be inserted on the image
$text = 'Hello, World!';

// Set the x and y coordinates for text placement
$x = 50;
$y = 100;

// Insert text on the image
imagettftext($image, $font_size, 0, $x, $y, $text_color, $font, $text);

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

// Free up memory
imagedestroy($image);
