You can create rollovers ONLY in SLICING MODE ("Mode->Slicing")

With Image Splitter you can create rollover effects, in which different states of an image are activated when a viewer performs a mouse action (such as rolling or clicking) over a slice. You can display an animation as a rollover state. Image Splitter adds JavaScript code to a slice’s cell in the HTML table to specify rollover states.When you create a rollover state, you can select the mouse action which activates the state (except for the first state in a rollover, which is always the Normal state, displayed with no mouse action performed.) You can delete individual states or all states in a rollover.

When you save an optimized document with rollover states, each rollover state is saved as a separate file. By default, rollover states are named using the corresponding slice name plus the mouse action that triggers the rollover state (i.e. logo_small2-2over.gif, logo_small2-2out.gif, logo_small2-2down.gif, logo_small2-2up.gif).

To convert selected slice to rollover image
- right-click on selected slice
- in the displayed pop up menu select "Add rollover images"

- to change rollover state image click "Change Image" button on Rollover window.
- to delete rollover state click on "Clear Image" button.

You can save your image as html file ("File->Save as...") or insert html code into existing html file ("View->Slice section source").
