Photo quality and text not centered on comments only page

[solarx]

1) The photo on this comments only page (+image link) has lower quality than the same photo seen in a regular gallery page.

Is there some code I need to add to this page to improve the photo display?

2) The page content is not centered. I copied the code from the following page which is centered.:scratch
