trouble centering main product image

[TecBrat]

I checked admin-configuration, and looked everywhere I could think of. I tore these two files apart and put them back together every way I could think of:
tpl_modules_main_product_image.php
tpl_product_info_display.php

still, my main product image is left aligned when I want it to be centered.

Can anyone tell me how to center this image?

(This is a 1.3.6 cart.)

This is not a PHP issue. The image position can be controlled in your stylesheet with

#productMainImage {}

[TecBrat]

... in your stylesheet with

#productMainImage {}

I forgot to come back and say thanks so, belatedly: Thanks!

Your reply helped.

I can find #productMainImage, #reviewsInfoDefaultProductImage etx but how do you use this to centre the product info image?

Cheers.

Something like

#productMainImage {
    margin: auto; 
    float: none;
    }

The float: none; is only necessary if the element has a float set elsewhere. If the float is set in the stylesheet, just remove that float instead of adding another declaration.
You can also use text-align: center; if the #productMainImage div has a fixed width and you want variable width images to center inside that space.
