center image in a div

Question

I'm trying to center horizontally an image in a div, and i don't understand why it isn't working... I've centered images so many times, and this time i just don't understand... Here is what i've tried...

CSS

#cabeca{
position: relative;
float: left;
width: 100%;
height: auto;
min-height: 290px;
margin: auto;
}

.cabecasize {
width:100%;
min-width: 968px;
height:auto;
min-height: 290px;
overflow:hidden;
left:0;
right: 0;
margin: auto;
}

.cabecafundo{
position: absolute;
width: 100vw;
left: calc(-50vw + 50%);
background-color: black;
height: 100%;
top:0;
z-index: -1;
}

.overcabeca{
overflow: hidden;
display: block;
margin: auto;
text-align: center;
}

HTML

<div id="cabeca">
    <div class="overcabeca">
        <img src="images/av61.png" alt="av61" class="cabecasize" />
    </div>
    <div class="cabecafundo">
    </div>
</div>

Any ideas??

everything is working the way it should... except the image, it just doesn't want to stay centered... It is already in a centered div, but when the page shrinks, an overflow happens and the img stay fixed, when it should go with the overflow and keep centered... thank for the help everybody! — André Mata, Oct 08 '15 at 09:59
Why are you giving the image a width of 100%? Because you're basically telling the image to fill it's parent — Steyn, Oct 08 '15 at 09:59
@SteynvanEsveld I need it to fill the parent, but i also have min-width, so that it stays the size I want... the size right now is perfect, i just need it to be in the center of the div (when the parent is smaller than 968px) — André Mata, Oct 08 '15 at 10:03

@SteynvanEsveld No the same... the solution there work for smaller inner divs... my inner div when I need it to be centered is bigger than the parent with overflow happening. — André Mata, Oct 08 '15 at 10:06

Check the below code, I hope it will helps you.

.wrap{

  height: 100vh;
  width: 100vw;

.midImg{
  margin: auto;  
  position: absolute;
  left:0;
  right: 0;
  top: 0;
  bottom: 0;
  height: 150px;
  width: 150px;
}

<div class="wrap">
