// Fig. 30.4: LogoApplet.java
// Customizing an applet via HTML parameters
//
// HTML parameter "animationdelay" is an int indicating
// milliseconds to sleep between images (default 50).
//
// HTML parameter "imagename" is the base name of the images
// that will be displayed (i.e., "deitel" is the base name
// for images "deitel0.gif," "deitel1.gif," etc.). The applet
// assumes that images are in an "images" subdirectory of
// the directory in which the applet resides.
//
// HTML parameter "totalimages" is an integer representing the
// total number of images in the animation. The applet assumes
// images are numbered from 0 to totalimages - 1 (default 30).
