Float image outside of parent container - css

Question

Firstly, I know this may seem like a duplicate of Positioning child content outside of parent container, but this is slightly different.
I've only had success floating an image outside of its parent container if I use an absolutely positioned div with the background-image set. Example of code used to achieve this:
.image {
position: absolute;
top: 0;
left: 0;
margin-top: -30px;
margin-left: -10px;
display: block;
height: 200px;
width: 140px;
}
Now I need to achieve the same with an <img /> element. What I'm hoping to achieve is something like this:
So the image should actually spill over on the left and right of the parent container. I've tried similar methids as given above, but without success. Any advice?

Answer 1

something like this?
.parent {
display:inline-block;
width: 100px;
height: 300px;
background-color:lightgray;
margin-left: 100px;
}
.child {
width: 200px;
height:100px;
border-radius: 100px;;
background-color:gray;
position:abolute;
margin-left: -50px;
margin-top:100px;
}
<div class='parent'>
<img class='child'/>
</div>
edit: as per the comments below this is what i see

Answer 2

See the method bellow
Wrap the image in a DIV
Add border-radius to achieve the egg like shape
Add overflow with a value of hidden to the image container
use an image that's bigger than it's container so that it will take on the egg like shape.
#square {
width: 300px;
height: 300px;
background-color: #6D9BBE;
position: relative; /* Relative to curtail overlap */
margin: 0 auto;
}
#square #eggy {
width: 380px;
height: 200px;
background-color: #8500B2;
border-radius: 50%;
position: absolute;
top: 50px;
left: -40px;
overflow: hidden;
}
#eggy img {
width: 390px
height: 240px;
}
<div id="square">
<div id="eggy"><img src="http://s9.postimg.org/xnmcpb0jz/use_this.png"/></div><!-- End Eggy -->
</div><!-- End Square -->
