Sticky string translation

After posting the first sticky story on my site I discovered the string sticky icon (the alt-text for the sticky icon) was not translated. I changed line 13 in node.tpl.php from this:

if ($sticky) { print '<img src="'.base_path(). drupal_get_path('theme','marinelli').'/img/sticky.gif" alt="sticky icon" class="sticky" />'; } ?>

to this:

if ($sticky) { print '<img src="'.base_path(). drupal_get_path('theme','marinelli').'/img/sticky.gif" '.'alt="'.t('sticky icon').'" '.'class="sticky" />'; } ?>

Now I can translate it with l10n_client.
