Add a Profile Picture in form in HTML and CSS

$("#profileImage").click(function(e) {
    $("#imageUpload").click();
});

function fasterPreview( uploader ) {
    if ( uploader.files && uploader.files[0] ){
          $('#profileImage').attr('src', 
             window.URL.createObjectURL(uploader.files[0]) );
    }
}

$("#imageUpload").change(function(){
    fasterPreview( this );
});
#imageUpload
{
    display: none;
}

#profileImage
{
    cursor: pointer;
}

#profile-container {
    width: 150px;
    height: 150px;
    overflow: hidden;
    -webkit-border-radius: 50%;
    -moz-border-radius: 50%;
    -ms-border-radius: 50%;
    -o-border-radius: 50%;
    border-radius: 50%;
}

#profile-container img {
    width: 150px;
    height: 150px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="profile-container">
   <image id="profileImage" src="http://lorempixel.com/100/100" />
</div>
<input id="imageUpload" type="file" 
       name="profile_photo" placeholder="Photo" required="" capture>

What you can do is to hide the input and just act as if it was clicked when the profile image is clicked:

$("#profileImage").click(function(e) {
    $("#imageUpload").click();
});
#imageUpload
{
    display: none;
}

#profileImage
{
    cursor: pointer;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<image id="profileImage" src="http://lorempixel.com/100/100" />
<input id="imageUpload" type="file" 
       name="profile_photo" placeholder="Photo" required="" capture>

Image preview

You can also give the user a preview of the uploaded image:

function previewProfileImage( uploader ) {   
    //ensure a file was selected 
    if (uploader.files && uploader.files[0]) {
        var imageFile = uploader.files[0];
        var reader = new FileReader();    
        reader.onload = function (e) {
            //set the image data as source
            $('#profileImage').attr('src', e.target.result);
        }    
        reader.readAsDataURL( imageFile );
    }
}

$("#imageUpload").change(function(){
    previewProfileImage( this );
});

Efficiency note: You can make it more efficient if you use createObjectURL instead of reading data as URL.

function fasterPreview( uploader ) {
    if ( uploader.files && uploader.files[0] ){
          $('#profileImage').attr('src', 
             window.URL.createObjectURL(uploader.files[0]) );
    }
}

As you can see here in MDN, the URL.createObjectUrl will just generate the URL for the file instead of having to load it into the DOM, which is definitely preferable for large files.

Circular image crop

To display the image cropped in a circle, you will need to give it an outer div and apply border-radius to it:

HTML:

<div id="profile-container">
   <image id="profileImage" src="aDefaultImage.png" />
</div>

CSS:

#profile-container {
    width: 150px;
    height: 150px;
    overflow: hidden;
    -webkit-border-radius: 50%;
    -moz-border-radius: 50%;
    -ms-border-radius: 50%;
    -o-border-radius: 50%;
    border-radius: 50%;
}

Complete solution

This snippet puts together all three steps:

$("#profileImage").click(function(e) {
    $("#imageUpload").click();
});

function fasterPreview( uploader ) {
    if ( uploader.files && uploader.files[0] ){
          $('#profileImage').attr('src', 
             window.URL.createObjectURL(uploader.files[0]) );
    }
}

$("#imageUpload").change(function(){
    fasterPreview( this );
});
#imageUpload
{
    display: none;
}

#profileImage
{
    cursor: pointer;
}

#profile-container {
    width: 150px;
    height: 150px;
    overflow: hidden;
    -webkit-border-radius: 50%;
    -moz-border-radius: 50%;
    -ms-border-radius: 50%;
    -o-border-radius: 50%;
    border-radius: 50%;
}

#profile-container img {
    width: 150px;
    height: 150px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="profile-container">
   <image id="profileImage" src="http://lorempixel.com/100/100" />
</div>
<input id="imageUpload" type="file" 
       name="profile_photo" placeholder="Photo" required="" capture>
