(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=”button.php3?button=yellowtext=Example” * will look for yellow.gif
and put the string “Example” on it. * * I use to have three buttons I
normally generate (one displays selected * item, one is for
mouseover(), and one is the default button). The source * images are
yellow.gif, white.gif and blue.gif – so my script assumes * blue.gif as
default if “button=” not specified – you may wish to change * this
below, its easy 😉 */ // ===========================[ check fo //r
