Please ask your question more clearly.
Do you have a div tag that contains your navigation links?
Have you used images for each of the links?
everything i resize the window - do you mean every time I resize the window?
The images stack up instead of disappear - why do you want the images to disappear?
How is your navigation structured? Do you simply have a div tag with a whole bunch of images nested between links or have you used <span> tags within or used a list?
Do they scroll virtually or horizontally?
I hope this helps you phrase the question more clearly.
