Hi. Already figured it out. What i did was this:
Installed ezstatic plugin and activate it.
Installed Static Front Page plugin and activate it (create a page called "Home", also)
Then, on this page, i insert this code (extracted from lazy-index.php and with some modifications)
< ?php
/* Don't remove this line. */
?>
<link href="./wp-content/plugins/lazy-gallery/lazy-style.css" rel="stylesheet" type="text/css">
<div id="content" class="narrowcolumn">
<div id="gallery">
< ?php showGallery();?>
</div>
</div></link>
Remember to check on the box that says "Execute as page content between..."
that's it. Now i have my lazy gallery as static home page on my blog. Check it out at http://jorgeonline.com
