Can you center an img based on its midpoint?

OK, here is what I am trying to accomplish. On this page:

I have sections that pull content, including an image, and put it on the page. I have the images currently there in the area I want them to be in. the issue is that I want them to be centered over each other, like they are here:

Normally, I would just put the images into a div, and then center them with the usual methods. In this case, however, I can not edit the html at all, so this is not an option. I have tried a lot of different things, but can not get this to work. Does anyone have a solution?

Thanks.

This is resolved. I just changed the image size, and I am good
