Answer 1

This will do. You don't need to open PHP tags inside PHP tags.

$sql_up="SELECT content FROM sp_uploads WHERE s_id= 'RC49557'";
$result_set=mysql_query($sql_up);

while($row_up = mysql_fetch_array($result_set))
 {
    $pp = $row_up['content'];
 } 

 echo "<td>  
 <img style='float:right; margin:5px; width:150px; height:150px; padding:10px;' 
 src='data:image/jpg;charset=utf8;base64, $pp' /> </td>"; 

I'm assuming the img data is correct.
