You use this dialog box to create a rollover image. A rollover image changes its appearance based on a ‘mouse’ state. Each rollover image must have at least two states: Normal Display and at least one Next Rollover.
Layer column: Shows the various forms of the image. Double-click a cell in this column to replace or insert an image or, for a text layer, change text in the Edit Text dialog box.
Display Event column: Indicates when that form of the image shows.
Popup column: To make the layer a popup layer, double-click to change this column from a blank to a check mark. (You cannot make the top layer or the first active layer a popup.)
Note: In this case, a popup appears next to the rollover when the pointer is over the image. If you have multiple popups, they all appear simultaneously each in its own line.
Image information columns: These columns show information about the layer. The first column indicates whether the layer is an image layer or a text layer. The second column shows the path for the image in an image layer or the text for a text layer.
Link to Internet Web Page check box: Select to link the rollover image to a web page. (The Link dialog box opens to specify the URL.) Clear to not have a link with this image.
Click the Advanced button to show or hide the toolbar and a preview.
Move Layer Up/Move Layer Down: Click to move the selected layer up or down in the listing.
Add Image Layer: Click to add a new image layer to the rollover.
Note: If you add a link to a rollover, you should not have more than three image layers in the rollover — usually two are sufficient. You can add extra layers and have them as ‘popups’.
Add Text Layer: Click to add a text-only layer. Double-click the text layer to add or edit text in the Edit Text dialog box.
Delete Layer: Click to remove the selected layer.
Preview area: Move the pointer over the image to see the various states of the rollover image.
You can change the URL associated with a rollover image, but you cannot adjust the rollover image, itself. To change a rollover, delete the existing one and create a new one.[need to verify this, it may be a bug]
