image rotated with javascript is not set to center though i have set it to top center in options

Did you try a forum search to locate the answer that has been answered before?

no but i have looked first page of this forum and forum in wordpress, and i think, this might be left unnoticed because if images are not too wide their horisontal position is hard to see and also two opacity overlay areas are hardly noticable, they are probably not needed by most people.

now after i have seen your reply i have tried to search for "rotating" and "header center" and i have not found my problem in first pages of search.

What other image options might you have turned on?
What is your url?
