Well, if you were using Opera I would suggest to you to switch to User Mode, but seeing that you do not have it and I'm not one to force my standards onto someone else...

^Using that will take you to the second page. To navigate to the next page, you need to change the address in your address bar so that it says "page=3" instead of "page=2", like this:
[noparse]http://www.serebiiforums.com/profile.php?do=editavatar&categoryid=42&page=3[/noparse]
Do that for each subsequent page and you shall be fine.
P.S. Also, when you're navigating to another category, you're going to want to make sure that the category value is correct (see category=42 in the example I gave you? That's for Kanto Battle Frontier). If there is no "page=#" value, simply type in "&page=#" at the end of your address, where # is the page you want to see.
Enjoy
