Image uploader on register view

I have a process where a user can register and add a picture of himself via an image file stored locally. The problem I am facing with a lot of image browsers openly available is either they require something as follows:

@using (Html.BeginForm("FileUpload", "Home", FormMethod.Post, 
                        new { enctype = "multipart/form-data" }))

I am not that knowledgeable in MVC,Can someone suggest the approach I should take in handling this issue?

Image should be uploaded on clicking Register. Almost all of the image uploaders I found had a dedicated button for uploading.
