Usually a logo is a small 100-300 px wide image like one that would be on a business card etc. and either left or center aligned on the web.

The remainder can be applied as a background image via css to the #logoWrapper tag. This can be a narrow 5-30px wide tile that repeats horizontally in your case I would rethink this and create a logo that represents your company and determine how else you want to use the auto and flag images
