Could you do this with HTML? You can use an editor to set the hot areas of an image and then display whatever you needed.

>Hi, i have a presentation in wich I have a map with regions, the goal is to click into each region and display a region specific information. It also has to have other buttons and processes. My question is how to manage images in a non square button like arranging a puzzle or to display a bitmap a control the regions. It wuold be nice to make some effects in the specific region as dimming the rest of the map once clicked or a onmouse over effect over the regions
