I just centered them for you. It was easy - you had one parameter in the template:
where "x" was either "l" (that's a lower case L, not an upper case I) or "r"
I removed the lines with the align parameters completely - if not stated, the default will be center. I could have left them there and simply change the "l" (for left) and "r" for (right) to "c" (for center).
One more thing you need to know about the align parameter - when an image is aligned center, text will not wrap around it. When it is aligned left or right, however, text will automatically wrap and you need to use an addtional template to stop the wrapping - that is:
If you put the clear template immediately after the image, then the text will not wrap at all.
I'm sure you'll have no problem un-doing what I did if you want, by using the Changes tab - otherwise, I would have simply answered here and not edited your work.
