Start Image from top of page Latex

I assume you issue a clearpage (or something similar) just before using begin{figure}...end{figure}, right? If this is the case, add mbox{} (or null) after the figure environment before starting a new chapter and your alignment should be fixed. Since there's nothing else on the page, LaTeX centres it, since that would be the best way to present the information.
