If the image is a piece of semantic data (like a profile picture, for example), then use an <img> element inside your <button> and use CSS to resize the <img>. If the image is just a way to make a button visually pleasing, use CSS background-image to style the <button> (and don't use an <img>).

Demo:

HTML:

<button id="close-image"><img src=""></button>
<button id="close-CSS"></button>

CSS:

button {
    display: inline-block;
    height: 134px;
    padding: 0;
    margin: 0;
    vertical-align: top;
    width: 104px;
}

#close-image img {
    display: block;
    height: 130px;  
    width: 100px;
}

#close-CSS {
    background-image: url( ' );
    background-size: 100px 130px;
    height: 134px;  
    width: 104px;
}

Output:

The simplest way to put an image into a button:

<button onclick="myFunction()"><img src="your image path here.png"></button>

This will automatically resize the button to the size of the image.

try this

   <input type="button" style="background-image:url('your_url')"/>

Why don't you use an image with an onclick attribute?

For example:

<script>
function myfunction() {
}
</script>
<img src='Myimg.jpg' onclick='myfunction()'>

Add new folder with name of Images in your project. Put some images into Images folder. Then it will work fine.

<input type="image" src="~/Images/Desert.jpg" alt="Submit" width="48" height="48">

Try like this format and use "width" attribute to manage the image size, it is simple. JavaScript can be implemented in element too.

<button><img src=""></button>

The topic is 'Embed image in a button element', and the question using plain HTML. I do this using the span tag in the same way that glyphicons are used in bootstrap. My image is 16 x 16px and can be any format.

Here's the plain HTML that answers the question:

<button type="button"><span><img src="images/xxx.png" /></span>&nbsp;Click Me</button>

General Answer:

<button style="background: url('icons/close.png'); background-size:cover"></button>

Since currently selected answer has some issues, posting this answer to save people trouble.

Make sure to give your button the width/height necessary to see your image as well as possible adding a "background-position" attribute to make your image show up as intended.

REACT VERSION:

<button style={{backgroundImage: "url('icons/close.png')"}}></button>   

To use Image as button create a button download button image and than open it in paint and note down the top left and right bottom coordinates

`<Img src =" button.jpg" usemap=" #button" >.   
<map name = " # button " >.   
<area shape ="rect" coords = " Top- left , bottom right " 
href = " page you want to open by button" > `  

You can use multiple< area> tag to create different button from just one image .

Note : There is one issue with this method that if you try to change the height and width of the image the pixels shift and your button won't work

For that change the button image size externally by photoshop or any other photo editor

That's it you have created your button without java script and with few lines of code
