Change:

<?$i=empty($i)?1:floor($i)?>

to:

<?$i=sprintf('%04d',empty($i)?1:floor($i))?>

I don't know how to do it in PHP, but the theorie is that if you want image 0002 to load , and then count 1 with it PHP converts 0002 to 2 and then count 1 with it. You would just need to check how long the variable is and add as mutch zeros as needed.

Same thing... Change <?=$i+1?> and <?=$i-1?> to <?=sprintf('%04d',$i+1)?> and <?=sprintf('%04d',$i-1)?>
