I am still testing the first nav button and that does not work. The navigation picture does not appears. Why is it? I am quite sure that the address is correct. I have Cloud.JPEG file inside of images folder. I already try changing the file name to Cloud.JPEG in my css and that does not work either.
Those two other images I didn't upload them to the web server. Don't worry about them. I only concern about the image that I upload on the webserver, which is the cloud server button. The same image has many buttons in it (CloudNav.jpg).
I only wonder why the image does not change on hover.
I have a better view offline. It's not my real site since I only uploaded several important images online. I only needs to get the logic correctly. If I can the cloud server button works then that's enough. I can get the rest to work and I only get stuck on the cloud server button and wonder why it doesn't change on hover.
Try to use firebug to check it.
The color of the cloud server button suppose to change from dark blue to light blue on hover.
