I like it when the images in posts are centered because for me the whole post looks a little bit more professional.
Therefore I use currently the hskip command:
$\hskipXin$ % with X being some real value, e.g., .5, 1, 2, ...
But doing this all the time manually, which includes the need to find a proper X-value that somehow centers the image, isn't that satisfying. ^^
Theoretically, can you tell which method I would choose to automagically center my images?
