For some reason, now that I've changed my CSS in Twenty Ten by creating a child theme, some of my photos are centering with the "center" command and some are aligning to the right. Also, some of them are staying full-size, regardless of what I do with the percentage resizing tool. I think the size problem is mainly if I have a photo as the very first element on a post, but the center thing seems arbitrary. I thought it might be because it was centering across the entire page instead of the column, but that doesn't make sense considering the results are inconsistent. Any ideas of what's going on?
Here's an example of where one photo centered but another didn't:
Here's an example of a photo that stayed large even though I reduced the size:
It initially opens with a small photo, then readjusts itself to being larger.
