gallery app, programming buttons

[krzysapp]

Hi,

I am begining with creating my own application for iPhone in Xcode (Objective C).
I have some basic knowledge, but I some help.

So, my app is going to be a gallery, which will basically allow you to browse through JPG and GIF files which will come with the app.

I have projected an interface in Interface Bulder. Whole page is covered by photo, and on the top of the screen there is a bar and two buttons:
- PREVIOUS
- NEXT
so you can browse throug picture

I have my jpg files loaded in xcode, but I need help with making the buttons work.

Any help will be appreciated.
