Padding on images in gallery

Hi,

When editing my images on my pages, there is a padding that is not easily removed.

/* Image borders */
img[class*="align"],
img[class*="wp-image-"],
#content .gallery .gallery-icon img {/* Add fancy borders to all WordPress-added images but not things like badges and icons and the like */
	border: 1px solid #ddd;
	padding: 6px;
}

Isn’t it just to set the padding to 0 and the padding in the gallery will be removed?

The picture linked is when hovering over an image on a page, showing a gray padding, which is my problem. https://data.fuskbugg.se/skalman02/4e622330c752e_border.jpg

I’m running the TwentyEleven (child) theme.
