Scrolling images horizontally and vertically

Hey everybody,
I have looked and tried scripts over and over on kirupas forum but I am still currently having problems and it is not working out. I am trying to design a photography site that has a vertical and horizontal scrolling movie clips. 2 seperate movie clips.
I would like for each scroller to have 2 buttons (which i’ve include) and when you mouseover/press the (left or right) / (up or down) button it will go in that direction. If you haven’t run the mouse over the buttons the movieclip will still marquee. Also I am trying that when you put your mouse over the image itself it will stop and you can click it like a button, and the image will load in the middlesection. Where the example image is.

I am not sure wheter it will load fast with external images, or just to put each image in a movie clip and let it load like that. Nested movie clips. Please, any help will be just fine. I bursting my head with these codes. Please help. Thanks you in advance
