What potential issues can arise when using PDF_load_image function in PHP?

When using the PDF_load_image function in PHP, potential issues can arise with memory usage if large images are being loaded. To solve this issue, you can resize the image before loading it using the PDF_fit_image function. This will help reduce the memory usage and prevent any potential memory-related errors. 

// Load the image file
$image = PDF_load_image($pdf, "image.jpg");

// Get the dimensions of the image
$width = PDF_get_value($pdf, "imagewidth", $image);
$height = PDF_get_value($pdf, "imageheight", $image);

// Resize the image to reduce memory usage
PDF_fit_image($pdf, $image, 0, 0, "scale=" . min(1, 800 / $width, 600 / $height));

// Use the image in the PDF document
PDF_place_image($pdf, $image, 100, 100, 0.5);
