Right, I understand that
if I use <td></td> it is blank space
if I use <td> </td> it is an empty cell
right now $length is set at 42 (this is arbitrary)
and there needs to be two empty cells at the end of
the last row. if length is 41 I will need 3 and 40
will need 4. but if I don't know what the value of
$length is going to be on a dynamic page such as
showing "x" amount of images from a folder. I need
for the loop to know how many "<td> </td>" to
echo out at the end depending on the $length;
I apologize if I am not explaining this very well.
I usually am quite concise.

ok, again, trying to understand "blank space"...but, try this:
if you print out <td></td> you'll get something i think you're referring to
as blank space...
try using a nonbreaking space in there...either or a space in the
code; this will force
the "emptiness" to show up...
