The <gallery> tag is handy for displaying images in all sorts of circumstances. Some will require the gallery to display on a large screen, other will require just a few images that won't spread completely across even a small screen. 

Right now, the gallery caption optional attribute always centers the caption. If the gallery is small compared to the width of the user's screen, the caption may be placed in a location far away from the set of gallery images it is meant to describe.

The default should be to align the caption to the left, so it will be near the images in all cases. Center alignment should be optional, if it exists at all. For expediency, I suggest just changing the behavior to left alignment, and an option for center alignment (and who knows what else) could be added later.
