What are some common challenges when uploading images using PHP forms?

One common challenge when uploading images using PHP forms is handling file size limitations. To solve this, you can set a maximum file size limit in your PHP code and display an error message if the uploaded file exceeds this limit. 

// Set maximum file size limit
$maxFileSize = 5 * 1024 * 1024; // 5MB

if ($_FILES['image']['size'] > $maxFileSize) {
    echo "Error: File size exceeds the limit of 5MB.";
    exit;
}
