I think you are not understanding the issue ...
The pages change from secure to non-secure as you move through the site ...
To manage this, you can use the built in functions for Zen Cart ...
For example to pull an image from the template images directory:
/includes/templates/your_template_dir/images
You would use:
PHP Code:
<?php echo zen_image(DIR_WS_TEMPLATE_IMAGES . 'filename.ext', 'alt tag here'); ?>
To pull an image from the /images directory you would use:
PHP Code:
<?php echo zen_image(DIR_WS_IMAGES . 'filename.ext', 'alt tag here'); ?>
