Overlay image on hover using only css - html

Question

I'm trying to overlay an image with a smaller image that has the background opacity of the first image when hover, using only css because i'm not able to edit the html.
Here is a sample HTML:
<div class="image">
<a href="http://www.example.com">
<img src="/uploads/2016/08/img1.png" class="rggclImgCenter">
</a>
</div>
Using CSS only, i thought would be something like this:
.image:hover {
background-image: url('https://cdn4.iconfinder.com/data/icons/ionicons/512/icon-ios7-arrow-right-128.png');
}
But it will only replace the image.

Answer 1

You could use the css pseudo element if you wouldn't like to (or cannot) modify the html.
Please be awared you cannot use :before or :after on img element
Here is the CSS:
img { max-width: 300px; } /* the image dimension */
.image a { position: relative; display: inline-block; } /* allow :before element positioning easier */
.image a:hover:before {
position: absolute;
top: 30px; left: 40px; /* Where to put the overlay */
display: inline-block;
content: ''; /* must have */
width: 300px; height: 164px; /* size of the element */
background-image: url('https://i.kinja-img.com/gawker-media/image/upload/s--pEKSmwzm--/c_scale,fl_progressive,q_80,w_800/1414228815325188681.jpg'); /* URL of the image */
background-size: 300px 164px; /* Resize the image as this dimension */
opacity: .5; /* Transparent rate */
}

Answer 2

Did not have the original image so used an image of my own. See if this helps.
You can also refer to this link: https://jsfiddle.net/askptx0y/
.image:hover {
background-image: url('https://cdn4.iconfinder.com/data/icons/ionicons/512/icon-ios7-arrow-right-128.png');
background-repeat: no-repeat;
opacity: 1;
}
img:hover {
opacity: 0.5;
}
<div class="image">
<a href="http://www.example.com">
<img src="http://www.freedigitalphotos.net/images/img/homepage/87357.jpg" class="rggclImgCenter">
</a>
</div>

Answer 3

Try adding a :before element on :hover.
.image a:hover:before {
content: '';
display: block;
position: absolute;
background-image: url('https://cdn4.iconfinder.com/data/icons/ionicons/512/icon-ios7-arrow-right-128.png');
}

Answer 4

Make image transparency:
.image a:hover image {
opacity: 0;
}
Show your background image
.image a:hover {
background-image: url('https://cdn4.iconfinder.com/data/icons/ionicons/512/icon-ios7-arrow-right-128.png');
/* add other properties */
}
