Hi. I have created 4 button graphics in photoshop since i had to use a specialist filter not availiable in fireworks. I import the first graphic and convert to button.

Then i expected to be able to import the the graphics i have made for selected, mouse over, down etc. But when i click on 'import a button' i can only import from a list of default buttons. My question is how can i put my graphics in this list which would allow me to import them

thankyou
