wp cycle picture size… general advice

I’m a relatively new user with a primitive understanding of PHP but some background in programming.

I’ve been trying to make my header images cycle through a series of pictures. I started using wp_cycle to do this.

I’ve got it working but i would like the images be centred and to spread across the page. What do I need to do to achieve this.

I’m using the twenty eleven theme.

After installing the plugin i took the code: <img src=”<?php header_image(); ?>” width=”<?php echo HEADER_IMAGE_WIDTH; ?>” height=”<?php echo HEADER_IMAGE_HEIGHT; ?>” alt=”” /> from the header.php and replaced it with <?php wp_cycle(); ?>

Any help much appreciated.
