Once again, I need help. Recursion and displaying multiple images in a window.

[scrap]

Hi all,

Once again I am in need of help. I am working on a program for my data structures class and I am ready to pull my hair out. Its almost the end of my semester and I have several programs to complete with little help from my prof.

The assignment is to write a program that displays images in a window and then recursively tiling the images to each corner. The program needs to prompt the user for 3 things, a scaling factor (.1 - .9) for decreasing the size of the images, a minimal size in pixels to scale down to, and 4 different images to be tiled.

I have been able to get it working using one image, but when I prompt the user for a second image file, the program will only display the second file. I could be wrong and it may display the first image fast and then repaint with the second image and I am just not seeing it. Right now, I have it set to recursively tile a single image to all for corners of the window. I need to be able to have different images at each corner, but I don't know how to do it. I can promt the user for more than one file, but I get lost after that.

Any help will be appreciated. I've been working on this for days and my professor isn't a big help. He just answers questions with questions and confuses everyone more than they were previously.

Below is my code...
Thanks
