Product listing - spacing

I am using 200x200 small image to display the products (zc default was 100). There's no space between those images, how can I add some space in between them?

thanks!

see attached screen shot

Assuming yu are using ZenCart 1.3.x - In your "custom" stylesheet find or add the following code and adjust for to your liking

.listingProductImage {
       margin: 1em;
       }

See if this helps

I am using 1.3.5, sorry for not mentioning before.

I can't find that in the custom stylesheet located at:
catalog/includes/templates/custom template/css/stylesheet.css

Laney...

Sorry for not making this stronger initially...

I've been so busy adding products and creating new stuff, only tonight I had a chance to edit the stylesheet! It worked beautifully!!! Thank you so very much!
