Change the images/backrounds in very simple flash games for kids

What I need - is to change the images/backrounds of the games. Everything else, including the sizes, should stay approximately the same. I don't have the fla source files - only the end result. Here is a link: [login to view URL] There is a main menu with a games and I only need to change some of them. Numbers from left to right. 3 subcat - 1 game (dandelions) change the background and the image 3 subcat - 2 game (puzzles) create one swf file so I could simply choose the background image that will be cut to pieces and put it in one folder. So in this case I can choose whatewer images I want and change them from time to time. 3 subcat - 3 game (balls) just change the images and the background, logic stays the same 4 subcat - 1 game (coloring) same idea as above, 1 swf file - 1 image, and I simply add the images as many as I want. Plus the buttons for color picking should be changed 4 subcat - 2 game (drawing) the buttons for color picking should be changed 7 subcat - 1 game (paired pictures) pictures should be different, the design needs to be slightly different 7 subcat - 2 game (pirate) pictures and background should be different 7 subcat - 3 game (find the difference) pictures should be different 7 subcat - 4 game (hedgehog) - pictures and background should be different Plus I need you to put the changed games to the menu. That's it. Don't know if you can edit this, or it's easier to create new with different images.
