Gaya Design is featuring a very nice tutorial (with source) on creating an image slider with a progress bar.

The slider uses the powerful jQuery Cycle plugin (see WRD post) which can rotate images with various effects.

The progress bar is created automatically to reflect the number of images that wi,ll be displayed.

Besides the look & feel of the slider, variables like speed of the slideshow & transitions can be set too.

Here are several examples provided to better findout how it functions.

CSS Globe has a chic animated progress bar built with CSS and an animated GIF file.

It is simply an EM tag above an animated GIF file which is blocking the part of the GIF file to creating the progress bar stop effect.

As this progress bar is only a visual trick, it can not show a "live" progress but only a static one which the percentage of progress to be shown was defined before the page is loaded.
