Full width images in 7.0 York theme

I'm trying to achieve a full-width style for my images, I looked into the forum, found some codes, but none of them worked out.

I will replicate in other 4 images below the ones I already designed in the page.

I tried this code:

.row sqs-row .yui_3_17_2_1_1670857839726_98 {
    width: 100% !important;
}

But it didn't worked. Even with only the yui part.

Thanks for the help.

You mean make 2 images fullwidth + remove white space between them?
