Change More photos (to the left, or right), 5 photos, not only 2 photos
 

How to change More photos feature (to the left, or to the right)
to be 5 photos, not only 2 photos


for example
- go to this page photopost.com/photopost/showphoto.php?photo=7920&title=1958-gmc-factory-4x4-suburban-napco&cat=5
- click More photos feature, to the right photopost.com/photopost/images/right.png
- there will be 2 another photos, this photopost.com/photopost/images/overlay-roundp.gif and this photopost.com/photopost/images/overlay-roundp.gif
- i want to showing 5 another photos at once, not only 2



is there settings about this, or which file that responsible for it?


Nb.
- i already tried find text 2 in showphoto.php, and replace to text 5, but its not it. Please give information or clue if you can
- i cant insert url currently, please open the image link in new tabs

The preview images show 5 images if there are 5 to show meaning in some cases there may only be 2 left to display depending on your start or stop photo.

I think no, i already tried this too with many images

like in example page photopost.com/photopost/showphoto.php?photo=7920&title=1958-gmc-factory-4x4-suburban-napco&cat=5 , if you click more photos to the right, there are still many images in the right, but still only add 2 images at once, can we set it to another number, like 5?
