# $i + +;

Example 1 (The information page has pagination and uses a simple paging regular):
Instance 2 (Information page is not paged, so the paging is empty):
Example 3 (the information page is not paged, so the paging is empty, the image is an absolute address, so the image address prefix is empty):
