I activated the post thumbnail by putting this in the functions.php
:
add_theme_support( 'post-thumbnails');
And this in the loop.php
:
<?php the_post_thumbnail('full', array ('class' => 'rollover')) ; ?>
And voila, the featured image appears on the main page, hopefully with the class of "rollover."
But what I want to do is turn this into a sprite. On my static HTML markup I wrote:
a.rollover: {
display:block;
width:300px;
height:200px;
text-decoration:none;
background:url(images/oldtable.jpg);
arollover:hover {background-position:-300px 0;
}
It works, but how do I make this dynamic (is that the word?) What do I substitute for the url so that the background url changes for each thumbnail? I tried this and it didn't work:
background:url(<?php wp_get_attachment_image_src());
Can someone help? Thanks.
