Answer 2

The column title will be repeated equal to the number of rows returned in the image table, you can not do anything to prevent it.
If you do group by title it will return the number of rows equal to the number of rows in the post table.
But if you elaborate more on what you actually want to do with the result I may help you.

Try this please :-
<?php
$a1 = "";
$stmt = $con->prepare("SELECT p.*,i.img,title,id
from post AS p INNER JOIN images AS i ON i.post_id=p.id");
$stmt->execute();
$result = $stmt->get_result();
if ($result->num_rows>0) {
while ($row = $result->fetch_assoc()) {
$title = $row['title'];
$img = $row['img'];
}
if($a1!= $title){
$activity="";
$activity.="<tr>
<td>$title</td>
</tr>;
}
$activity.="<tr>
<td><img src="images/<?php echo $img ?>"height="20"width="20"/></td>
</tr>";
$a1=$title;
}
?>
