PHP or CSS problem: Modifying a Template.

Hi there.

I’ve been using WordPress for a short time now, and am having fun blogging. I am an amateur photographer, and want to start a photo blog. I figured that I may as well try to modify a WordPress template to get the result I want.

In terms of layout I am almost 100% happy, but there is one small problem with the ‘newer’/’previous’ links.

I want them to appear just underneath the photo, and above the caption. It works fine on the most recent post, when only the ‘previous’ link is showing. But once you view the earlier posts and both ‘newer’ and ‘previous’ links are displayed, the layout displays incorrectly.

I’ve tried displaying only the ‘newer’ link, and the problem still exists. But when the ‘newer’ link is removed, the page displays correctly.

The CSS that I’ve used floats these links to the left and right. To display the links under the photo and above the caption (effectively in the middle of the post) I’ve used a relative positioning of:

top:500px;

My main problem is that I don’t know PHP, so am effectively operating blind here.
Any help would be appreciated.

Thanks in advance!
