Creating a Space between two images in Flash

This is the gallery I am working on. It used to have four boxes across, but I cut it down to two (which is what I want).

I want to make the boxes bigger, and I have figured out how to do that, but I am having a problem trying to get more of a space between the images. I am new to flash, but I can read some coding. I have looked everywhere and can’t figure it out. When I open the flash doc, I can see the background and just one of the images, so it’s basically on ‘repeat’ to show four images (now 2).

Can anyone look at this actionscript and see if they can help me locate where the space between the two images would be? I would Soooo appreciate it:

I’ve done a search for ‘width’ and ‘space’ in the actionscript and got nothing that worked.

I have been able to figure out how to make the images bigger, but when I do this, they smash together and there is absolutely no space between them.

I wonder if the spacing is set to 0 or something because I know there is spacing now, but it doesn’t stay there when the images get bigger.

I have Flash 2004
Thanks
