Decadency

Jaka wtyczka jest polecana zamiast tego?

I jeszcze pytanie, co oznacza ta część kodu i co się stanie jeśli to skasuję:

<?php if ($popup == 'On') { ?><a href="<?php echo $full[0]; ?>" rel="prettyPhoto

[pp_gal]" title="<?php if ($alt) { echo str_replace('"', "", $alt);  } else { echo the_title(); } ?

>"><?php }?><img src="<?php  echo $thumb[0]; ?>" alt="<?php if ($alt) { echo str_replace('"', "", 

$alt); } else { echo the_title(); } ?>" title="<?php print_r($caption); ?>" class="scale-with-grid" 

data-thumb="<?php  echo $thumb[0]; ?>"/><?php if ($popup == 'On') { ?></a><?php }?>
                  <?php $counter = 2;
                  while ($counter < ($thumbnum)) :
                    if ( ${'thumb' . $counter}) : ?>
                      <?php if ($popup == 'On') { ?><a href="<?php echo ${'full' . $counter}[0]; ?>" 

rel="prettyPhoto[pp_gal]" title="<?php if (${'alt' . $counter}) { echo str_replace('"', "", ${'alt' 

. $counter}); } else { echo the_title(); } ?>"><?php }?><img src="<?php  echo ${'thumb' . $counter}

[0]; ?>" alt="<?php if (${'alt' . $counter}) { echo str_replace('"', "", ${'alt' . $counter}); } ?>" 

title="<?php if (${'caption' . $counter}) { echo str_replace('"', "", ${'caption' . $counter}); } ?

>" class="scale-with-grid" data-thumb="<?php  echo $thumb[0]; ?>"/><?php if ($popup == 'On') { ?

></a><?php }?>
                    <?php endif; $counter++;
                  endwhile; ?>
