What is the code for pagination display??

PHP Code

  
  
  
  "; $y + +;}?" >

I have shown here 50 images of the same directory as this file "Pic1.jpg~pic50.jpg"
Now I want to show these pictures paginated, showing 10 pictures per page, and inserting the "previous page, next page" connection. How to write this code??

------Solution--------------------
The same get a variable to determine whether it has exceeded the $y value is not the words from this variable offset 10-bit loop output.
As for the next page this is to pass the above variables to the page. The previous page was minus 10.
