APEX

Hi

I have a custom button.

I have imported two images for the button into Apex.

One image for the button to be displayed normally and the other image to be displayed only when the mouse hovers over the button.

How do I make the button change appearance when the cursor hovers over the button?

(I noticed the standard buttons have an orange edge on mouse over and different look when pressed suggesting 3 images are used)

My custom 'button style' is image.
'Button image' is one image (imported)
'Image Attributes' is blank
'Button Attributes' is greyed out.

Other options for 'button style' are HTML Button or Template Based Button - perhaps I should use the HTML button but I don't know how to set the button attributes.

thanks in advance, pgj
