I need help editing a gallery

Hi
I’m pretty new with flash and I found 2 photo galleries that I like and I would like to do galleries for my photos just like those I found but I have trouble editing them.
Anyone can help me telling me a little about what I should do to add my pictures into this galleries?
Here are the address where I found them:

Thanks

File–>Import to library.

Import your pics into the library.
A much better way to do that is follow this tut:

Importing pics into library makes your file too large for use on the net.
