Responsive content if set a fixed point of begin

[SrPatinhas]

For example if we have a gallery of images, and we want a certain position / order, we could set a initial value of the width for example and then the content would get more or less size.
Example:

$('#container').freetile({
    selector: '.thumbs',
    size: 1440px
});

and then if the window had like 1000px the content would have like 90%

the layout that was made for the 1440px was this one

and now what happens is that the image just lost the wanted layout

Any help?
