That's not so pretty. Are you parsing variable names to get data?
Because it would be a lot easier (client-side scripting problems aside)
for you to name your arrays like so:

<input type="text" size="2" name="rows[<?=$imageid=?]['size1']"
value="<?=$size1=?>" />

So that when you submit the form, you'll get an array like:

$_POST['rows'] = array(
	'your_image_id' => array(
		'size1'		=> 'size1_value',

Using the bare '[]' at the end of a variable name is like using it
within PHP code:

$foo[] = 'bar';

Which just assigns the string 'bar' to the next integer index of array
$foo. Associative arrays are much more easy to work with in dynamic
forms like this, since you *know* where your data will be when you get
it in the request. $foo would be much more predicable if we assign
values to it using specific keys like so:

$foo['bar'] = 'baz';

Try my example above. :)
