alright, starting to work on a new website and just some fundamental things need to be worked out. I have a potential idea or at least the beginning of an idea here: http://www.geocities.com/ihrimtest/potentialidea.jpg
now, there are a few questions:
one i want this to be just the background image, and I'm realizing on different resolutions it doesnt fit perfectly... a site that does what i want in terms of the beginning or at least the background is www.pixelranger.com the long rectangle goes from bottom to top and u would never have to scroll left or right for excess image, does anyone know how to create this type of background?

Secondly, if u click enter on the pixel ranger site, there is a background and flash that from what I understand, which could be completely wrong sits ontop of the background and imitates it so it can then morph the background... is that the case? if it is how would I be able to line up the background and the flash properly to create this effect?

hopefully I stated my questions clearly but if I have not please ask for clarification as I really do want to find answers to my problems... Thanks in advance!
