JPGs loaded with XML

Question

Please help me with this issue. I have tried to solve this
myself without luck. I am very close!

ISSUE: get the "next" and "previous"-buttons to work
properly.
DESCRIPTION: if you browse through a portfolio, you should
easily be able to click on the next image. At the moment it is not;
when you have clicked on a thumbnail to view the larger version,
you have to go back to the category to click on a new thumbnail.
I added the "next" and "previouos"-buttons to the project.
This is how it works:

sample.
When you have clicked on a thumbnail, ex. in the fashion
category and click on the 'next' button, it begins to show the last
image on the xml-list. When I click next again, it shows the second
last, and so on.
QUESTION: how can I make it show the next image listed after
the current image viewed in the xml-file?
THE CODE:

Answer 1

this should work fine if the variable visesNaa is set when
the user clicks on a specific thumbnail.
you'll need to set antallBilder somewhere too... that part
seems to be working on the linked site though, so you must be
already.
what might be a better idea for structuring your code would
be to put the line:
fileName = alleFilnavn[visesNaa];
in your imageView function. then you would just have to set
visesNaa and call imageView regardless of whether the user clicked
on a thumbnail or clicked on next/back. if you want to get even
tidier, pass the function the variable visesNaa as a
parameter.
