Problem with non responsive image

Think I have a easy issue for all people here.

I received some help from stack overflow and now I need to do final adjustment.

I have changed the width of a specific page in WordPress using this code:

.page-id-247 .hentry, .page-id-247 .aligncenter {
max-width: 700px !important;
}

The only problem after resizing the width is that the image don’t resize any longer.

If you have any input on this I would be very happy?

Thanks,
