I have been doing some layout in Photoshop for a basic website. I have one .jpg which will be my background. I have created some thumbnails (filmstrip area), and I want them to highlight as the mouse goes over them. At the same time I want the image at the bottom to change to correspond to the thumbnail.
I know how to do the behavior "swap image" part. What I am unsure of is whether I should make image maps over the thumbnails or if I should make slices for each thumbnail in Photoshop.
