Joomla

Did you have any problem with one of the YooTools called YooGallery about pagination. This tools is very beautiful if showing photo album for website. A lot of beautiful different frame, there is very nice slideshow, nice lightbox but why I cant find pagination? Why? I thought I might be missing something or maybe Im to stupid to find out or maybe there is no pagination.

btw find out more about this plugin in

http://tools.yootheme.com/extensions/yoogallery

So I started to ask uncle google about this problem, and I found this forum that giving a very good answer:

http://forum.joomla.org/viewtopic.php?p=1549058

So the guy with nickname: mejim707 modified the php code to allow us to add pagination.

Tested on Joomla 1.1+ and 1.5+ with and without sef rewrites.

How to used it:

first you set yoogallery mambot call to limit the thumbs per page  then add
pagemax=[12]
Replace 12 with whatever number you want.

So, here it goes, open the gallery.php file

change the code into this code:
