Inline-block display of divs with position relative - css

Question

I have a series of images each with his own overlay. How can I have them aligned like inline-blocks? I tried adding adding display: inline-block;to .image-wrapper but the images are always all positioned in the top left corner of the div.container (Here is a jsfiddle).
Here are the html and css
.container {
position: relative;
}
.image-wrapper {
position: relative;
display: inline-block;
}
.tweetty {
position: absolute;
overflow: auto;
top: 0;
left: 0;
}
.image-vest {
position: absolute;
top: 0;
left: 0;
background-color: #00f;
width: 220px;
height: 300px;
opacity: 0.4;
color: #fff;
}
<div class="container">
<div class="image-wrapper">
<div class="tweetty">
<img src="http://www.picgifs.com/clip-art/cartoons/tweety/clip-art-tweety-191375.jpg" />
</div>
<div class="image-vest">Tweetty-one</div>
</div>
<div class="image-wrapper">
<div class="tweetty">
<img src="http://www.picgifs.com/clip-art/cartoons/tweety/clip-art-tweety-191375.jpg" />
</div>
<div class="image-vest">Tweetty-two</div>
</div>
</div>
EDIT:
revised css with dfsq suggestion to remove position:absolute; from .tweetty.
Quoting dfsq comment:
"Elements with position absolute don't contribute to the width and height of their parent container. So the image-wrapper divs just collapse as if they were empty if all children have position:absolute; "
.container {
position: relative;
}
.image-wrapper {
position: relative;
display: inline-block;
}
.tweetty {
overflow: auto;
top: 0;
left: 0;
}
.image-vest {
position: absolute;
top: 0;
left: 0;
background-color: #00f;
width: 220px;
height: 300px;
opacity: 0.4;
color: #fff;
}
<div class="container">
<div class="image-wrapper">
<div class="tweetty">
<img src="http://www.picgifs.com/clip-art/cartoons/tweety/clip-art-tweety-191375.jpg" />
</div>
<div class="image-vest">Tweetty-one</div>

</div>
<div class="image-vest">Tweetty-three</div>
</div>
</div>

Answer 1

I fiddled with the fiddle, and this seems to work. removed all the positioning from all but the vest. Used the inline-block display mode. Set top to -300px, and also the bottom-margin, otherwise you get a gap below the images.
.container {
/* position:relative;*/
}
.image-wrapper {
/* position: relative;*/
display: inline-block;
}
.tweetty {
/* position:absolute;
overflow:auto;
top:0;
left:0;*/
}
.image-vest {
position:relative;
top:-300px;
margin-bottom: -300px;
left:0;
background-color:#00f;
width:220px;
height:300px;
opacity:0.4;
color:#fff;
}
<div class="container">
<div class="image-wrapper">
<div class="tweetty">
<img src="http://www.picgifs.com/clip-art/cartoons/tweety/clip-art-tweety-191375.jpg" />
</div>
<div class="image-vest">Tweetty-one</div>
</div>
<div class="image-wrapper">
<div class="tweetty">
<img src="http://www.picgifs.com/clip-art/cartoons/tweety/clip-art-tweety-191375.jpg" />
</div>
<div class="image-vest">Tweetty-two</div>
</div>
<div class="image-wrapper">
<div class="tweetty">
<img src="http://www.picgifs.com/clip-art/cartoons/tweety/clip-art-tweety-191375.jpg" />
</div>
<div class="image-vest">Tweetty-three</div>
</div>
</div>
