Changes by SaWey

01/19/08 fixed proper working of fixed image sizes

01/07/08 - added path_to_images, for easier adding path of images

01/07/08 - added go_to_last_image_on_exit, so you can set if you want to return to the last seen image in the slideshow

??/??/07 - added redirect to page of last image in slideshow



History of changes by ahavriluk:

07/23/06 - fixed issue with background color being green in FireFox. Made music player appear and hide depending on

07/21/06 - added color background support for music player. To change the skin look at createMusicPlayer function.

07/19/06 - added changeImageByTimer() function which helps to load the image while the entire page is loading.

07/17/06 - fixed a bug when slideshow doesn't start if navigation buttons (next/prev) were used first and slideshow=0 at start
