What are the potential challenges or limitations when trying to achieve a specific design, like the one shown in the image, for a form with image upload in PHP?

One potential challenge when trying to achieve a specific design for a form with image upload in PHP is ensuring that the uploaded image is displayed correctly on the form after submission. This may require handling the file upload, storing the image in a designated folder, and then retrieving and displaying the image on the form. Additionally, validating the file type and size to prevent any security risks or issues with displaying the image is important. 

<?php
// Handle file upload
if(isset($_FILES['image'])){
    $file_name = $_FILES['image']['name'];
    $file_tmp = $_FILES['image']['tmp_name'];
    $file_type = $_FILES['image']['type'];
    $file_size = $_FILES['image']['size'];

    // Validate file type and size
    $allowed_extensions = array('jpg', 'jpeg', 'png');
    $file_extension = pathinfo($file_name, PATHINFO_EXTENSION);

    if(!in_array($file_extension, $allowed_extensions)){
        echo "Invalid file type. Please upload a JPG or PNG file.";
    } elseif($file_size > 5000000){
        echo "File is too large. Please upload a file smaller than 5MB.";
    } else {
        // Store the image in a designated folder
        $upload_path = 'uploads/';
        move_uploaded_file($file_tmp, $upload_path . $file_name);

        // Display the uploaded image on the form
        echo '<img src="' . $upload_path . $file_name . '" alt="Uploaded Image">';
    }
}
?>
