Picture gallery loop

I need a picture gallery, probalby (even better) based on admin/avatars.php. It needs to have 4 modes and will be used for my portfolio. The thing is - there must be a seperating slash used as shown in these examples, can it be done (I know the way I did is wrong, but at least it works in mode 2)

PHP Code:

---

Mode 1:
1 (without slash)
2 (without slash)

Mode 2:
1 / 2
3 / 4

Mode 3:
1 / 2 / 3
5 / 6 / 7

Mode 4:
1 / 2 / 3 / 5
6 / 7 / 8 / 9 

<? 
$cols = "2"; // 2 row mode 
$query = "SELECT * FROM imglib WHERE cat='\$c' ORDER BY \$so \$o LIMIT \$initialPhoto, \$it"; 
if(!$result = mysql_query($query)) echo "Query failed"; 
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) { 
    $data = $row["url"]; 
    if ($i == 0) { 
        echo "<tr>"; } 
    if (($i % $cols) == 0 ) { // if (\$i == \$cols) 
        echo "</tr><tr>"; 
        echo "<tr>"; 
        echo "<td width=\"540\" height=\"30\" colspan=\"2\" class=\"BoxBellow\">"; 
        echo "<p>&nbsp;</p>"; 
        echo "</td>"; 
        echo "</tr>"; 
        $i = 0;  } 
    if ((1&$i)) { // odd shows no dotted line 
    echo "<td width=\"270\">"; 
    } 
    if (!(1&$i)) { // even shows a dotted line 
    echo "<td width=\"270\" class=\"Boxright\">";    } 
    itemplaceholder(); //common 
    echo "</td>"; //common 
    $i++;     } 
    if ($i != $cols) 
    echo "</tr>";?>

am I missing something? you said that works in mode 2 yet you are not echoing anything from the database. also you html has a lot to be desired, you open 2 <tr> and you don't close other cells.

so you are trying to make mode 4 happen?

you have to get the total number of rows from the query and if over a certain amount then you do which ever mode you want

3 and 4 not working for me. Can you help out?

and like I said, how is 1 and 2 working when you don't even have anything outputted? I told you what to do, I am not writing the code for you but I will help you out.

But 2 works, doen't know how, but it does.

I don't either, it shouldn't
