What potential issues can arise when using a WYSiWYG editor for image insertion in PHP?

One potential issue that can arise when using a WYSiWYG editor for image insertion in PHP is the security risk of allowing users to upload and insert potentially harmful files. To mitigate this risk, you can validate the uploaded images to ensure they are safe before inserting them into the editor. 

// Validate the uploaded image file before insertion
if(isset($_FILES['image']) && $_FILES['image']['error'] == UPLOAD_ERR_OK) {
    $allowed_extensions = array('jpg', 'jpeg', 'png', 'gif');
    $file_extension = pathinfo($_FILES['image']['name'], PATHINFO_EXTENSION);

    if(in_array($file_extension, $allowed_extensions)) {
        // Insert the image into the editor
        $image_path = 'uploads/' . $_FILES['image']['name'];
        move_uploaded_file($_FILES['image']['tmp_name'], $image_path);
        echo '<img src="' . $image_path . '" alt="Uploaded Image">';
    } else {
        echo 'Invalid file format. Please upload a JPG, JPEG, PNG, or GIF file.';
    }
} else {
    echo 'Error uploading file. Please try again.';
}
