Embed image in a <button> element

I'm trying to display a png image on a <button> element in HTML. The button is the same size as the image, and the image is shown but for some reason not in the center - so it's impossible to see it all. In other words it seems like the top right corner of the image is located at the center of the button and not at the top right corner of the button.

This is the HTML code:

<button id="close" class="closing" onClick="javascript:close_clip()"><img src="icons/close.png" /></button>

Update:
What actually happens, I think, is a margin problem. I get a two pixel margin, so the background image is going out of the button. The button and the image are the same size, which is only 20px, so it's very noticable... I tried margin:0, padding:0, but it didn't help...

Solution 1:

You could use input type image.

<input type="image" src="http://example.com/path/to/image.png" />

It works as a button and can have the event handlers attached to it.

Alternatively, you can use css to style your button with a background image, and set the borders, margins and the like appropriately.

<button style="background: url(myimage.png)" ... />

Solution 2:

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>).

HTML:

<button id="close-image"><img src="http://thinkingstiff.com/images/matt.jpg"></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( 'http://thinkingstiff.com/images/matt.jpg' );
    background-size: 100px 130px;
    height: 134px;  
    width: 104px;
}

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.
