Hi, I am designing for a clothes shop and want to showcase a few pieces by providing images of them where the user can click arrows back and forward to see the piece from different angles. Do you know of a software I can use to create this effect that will not require the site user to install a plug-in.
Thanks
Julia

If you want it truly 3D that the user can look around freely you'll need to use some sort of plugin, even if it is just flash.

If you just have a few images I would either make a few identical pages with just the image changed (easiest) or use JavaScript and the onClick method of the link to change the image.
