Hello I am a new web designer and I want to know how to have your buttons that you would put across the top of the page do a drop down menu when you mouse over them? Im talking about pre-made graphic buttons that you make in Paint Shop Pro because this person wants specific-looking buttons to match their background set.

have a look

I wouldnt use javascript, rather look for CSS Drop Down menu tutorials. (simply using background images for list elements).

I have a version of suckerfish dropdowns on my site that have background images. Maybe this will help.

I love suckerfish because it's a nice small script. light java / css
