Products images display

I have problems with my products page and images products.

In all products, image are too big and on the top.
I try several metod but doesn’t work.

Also i choose 4 products in each line and have only 2.
I change it in theme options but issue is the same.

Hope you can help me ?

HI Geoffrey

First i thought this is a code or settings problem but then i discovered the problem is in images itself, your images have huge white space around the main character,

“Also i choose 4 products in each line and have only 2.” - i can clearly see 4 columns on the main page, have you fixed it? if no then please show me it on the screenshot
