I can't figure it out Sorry I'm new to HTML.

I have a bunch of upper and lower (left) navigation buttons. After the last button there is a stretch bar image which needs to stretch all the way to the final image. The image at the end needs to stay at the very end regardless of the users resolution/monitor size etc.

I need it to look like this:

Here are the button images: (don't worry about colors)
bottom: http://postimage.org/image/vkli5f6vj/
end: http://postimage.org/image/6slvy6pov/
stretch: http://postimage.org/image/5eu92vqfj/
top: http://postimage.org/image/ix15f62kv/

Thanks in advance!
