This is a continuous scroller:

This is a page scroller:
You control the page size, borders all colors, etc. These could be pictures of your gym equipment, cars on your lot or houses for sale. Each picture can be annotated with comments, prices, dates, etc.

And this is a presenter:
Different Status Bar messages with each image, if you wish! All images can be turned into links, again with full control of colors, text, images, sound per slide or for the whole presentation. Images cease to move upon mouse roll-over. Think of PowerPoint on steroids! Of course we can change the size of the box and the split ratio.
We can also use buttons, like those of a tape player, so your site visitors can control which picture they see in both the presenter and the page scroller.
