Allow users to choose how many images they want per page

Hey,

As this is my first post here, I'll start by a big thank you to the gallery2 developpment team, and everyone who worked on features, themes, etc. You guys are doing an amazing work.

Now my question : I may have missed it, but I couldn't find any mention on the forums of such a feature. I'm using Gallery2 with the siriux ijonized theme, and I'd want the users to be able to select on a drop down menu how many pictures they want to see per page (5, 10, 20, 50, ..., all). I wouldn't mind changing the theme I use if that's how I should do it. Would anyone be able to help me on this one ?

Thanks a lot !
