I’m working on a template where I want to use pictures instead of text for the “Newer entries” and “Older entries” links.
I tried something like <?php next_posts_link('<img src= [...] />', 0); ?>, but it didn’t work. So I took a look at the forum and tried <?php next_posts(0, false) ?> to just get the URL of the next posts listing page. But the disadvantage (of course) is that it displays the next/previous-images every time, even when there are no “more pages” to display.
So my question: Is there a function/method to find out, if next/previous posts exist? Or is there even a more elegant way to get what I want (images instead of text links)?
