Topic: Vertical "scrolling" ?

Hi, I'm currently having a lot of fun (and a bit of frustration wink) customizing SimpleViewer. I have set the gallery in question to have 1 column and 5 rows, so that the images are aligned like this:

[01] [06]
[02] [07]
[03] [08]
[04] [09]
[05] [10]

(currently ten images, but I plan to have more).

However, what I would like to have is have the first five display like this:

[01]
[02]
[03]
[04]
[05]

Then, upon clicking the "next thumbs" button, I'd like to have this:

[02]
[03]
[04]
[05]
[06]

or alternately this:

[06]
[07]
[08]
[09]
[10]

but in either case, I'd like it to scroll vertically rather than horisontally. I have been trying to edit the source a bit, and I can sort of get the tween to move vertically, but it still seems to arrange the images like the first example, so when I scroll vertically, I can't see any new images. If that makes sense. Anyone that have done this / have some pointers?

Any help much appreciated!

thanks,

Meke
