Output wp_link_pages as raw url

Question

My post content looks like this

<img src="http://linktoimage.jpg" alt=""/>
<!--nextpage-->
<img src="http://linktoimage.jpg" alt=""/>
<!--nextpage-->
<img src="http://linktoimage.jpg" alt=""/>
<!--nextpage-->

Basically I'm trying to make a web comic book so I have made each image to split onto multiple pages using the <!--nextpage--> feature. Now the problem is I want my images to be linked to the next paginated post. I can't use <?php wp_link_pages(); ?> to make a hyperlink on the image cause wp_link_pages outputs it as html and I need it as raw url and I don't need prev & next link. I only need a next link on the image.

Is this a way to make my images to be hyperlinked to the next paginated post?

Answer 1

If you take a look at the link generated by the <!--nextpage--> tag, it just appends /2 for page 2 /3 for page 3 and so on. In other words, it adds a query string page=page_number to your post link.

So all you have to do is insert an hyperlink to your image with the next page number for that image.

you still need to add the <!--nextpage--> tag because that will break your post in multiple pages. If you don't all your images will all appear on each paginated page.
