First off, I bring up my left.html page, where the navigational icons are located. By double-clicking that filename in the Site Window, left.html appears in the Document Window, in the Layout format. The images I’m going to use need to be named, and I don’t mean that they need filenames: They need a title that the script can work with. So first I place my blank image (which is actually two brackets with a big, blank space between them) below my icons using the Palette. Then I go to the Image Inspector and hit the Spec tab, where I can modify certain characteristics of the image, such as the border size and the ALT text. This is where I can name the images. In the Name space I title this one blank. Now I have something I can use as my target in the script.
I click on the sun icon image, thereby turning the context-sensitive Inspector into the Image Inspector, complete with an Actions tab on the far right. I select this tab to specify which Actions I want to take place.
So I’ve set the Action, and the bottom half of the window comes to life. Note that you are told which browsers support this Action (in my case, Netscape 3 and higher and Explorer 4 and higher) – a handy piece of information when deciding if these showoff scripts are worth the trouble.
Now I need to target this Action, in other words, tell GoLive which image I want to change when the rollover takes place. The pulldown Image menu lists all of the images that have been named, so I select the only one that appears there: blank. As it says at the bottom of the window: “Images without names cannot be a target for this action.”
Finally, I need to fill in the Link blank. This tells GoLive which image you want to swap with blank. Using point-and-shoot, I select nav_bio.gif – this is my image of the word Biography – from the Site Window.
