Welcome to TalkGraphics Joe

Mouse Off is the base layer. Everything on this layer is visible when your page loads.

You can create a new layer, place a photo on this layer, and link to the photo layer from the Mouse Off layer. The photo will not be visible when the page loads until the visitor clicks the link. The link can be a basic link, click something linked to that layer. It can also trigger the image when the cursor passes over a linked object or text. This would be a Mouse-over link.
