    /* PHP3 Button generator, (c) 2000 by IzzySoft (izzysoft@buntspecht.de)
    * License: GPL (and it would be nice to drop me a note that you find it
    * useful - if you use it. And, of course, I am very interested in
    * enhancements you made to the script!
    *
    * Purpose: generate buttons with text passed by parameter.
    *
    * possible parameters to the script:
    *button- input gif image. Just the part of the filename before the dot.
    *The specified image file is expected in the same directory
    *as this script resides in.
    *font - font to use (1 - 5; 1 is very small, 3 medium, 5 normal size.
    *The script will automatically use a smaller font if text is
    *too long for selected size.) Default: 5
    *text - the text to be put on the button. Will be centered.
    *textcolor - color for the letters. Default: white.
    *in this example code only blue, white and black are defined;
    *but you can add custom colors easily.
    *width,heigth - width and heigth of the button. Useful only if target
    *button should have different size than source image.
    *
    * Example for usage:
    * <IMG src="http://img.jcwcn.com/attachment/portal"
