image problem

Hello! i Am currently working on this site for a company that just hired me and everything is great, but the WP Catalouge is giving me a hard time.

1). First things first the images line up well, but they are not centered in the page it look slike they are alligned left as they are real close to the catalouge category navigation bar. What code can i input to try and center these? (I’ve tried all the codes posted on the forum)

2.) The more pressing issue is that although i can view the image thumbnails well and the thumbnails themselves seem centered whenever i click on the thumbnail to go specifically to the product details page the image that is there is always off centered. I even cropped the images myself to the exact size of the gallery image dimensions and it still gives me a hard time.

I’m new to wordpress and this is killing me if anyone could help i’d really appreciate it. the site is https://www.deconelpanels.com and the problem occurs on the “Styles” Page.
