I think I see the issue, you would have to be able to style the containing div for the data entry rather than whatever is inside, because that one's left-aligned and any alignment you specify will be relative to that container. If you can't use CSS (or ask your admin), this hack would effectively center the image, although it doesn't really feel clean to me...:

However, you will need to specify image-size as a number only.

I tried this in the Web console, so I'm not entirely certain it will work as intended in the template, but the idea is there.
