Programmatically access user profile + client object model SharePoint 2010

Here is a Code snippet for retrieving user profile picture using Client Object model – ECMAScript . I am passing the userId from the front end to a javascript method called “getUserProfile()” to retrieve the user profile info. The method onQuerySucceeded will get you the user Profile info.
function getUserProfile(userID)
var clientContext = new SP.ClientContext.get_current();
var web = clientContext.get_web();
var userInfoList = web.get_siteUserInfoList();
var camlQuery = new SP.CamlQuery();
camlQuery.set_viewXml(‘<View><Query><Where><Eq><FieldRef Name=\’ID\’/>’ +’<Value Type=\’Number\’>’ + userID + ‘</Value></Eq>’ +
this.collListItem = userInfoList.getItems(camlQuery);
clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded),Function.createDelegate(this, this.onQueryFailed));
function onQuerySucceeded(sender, args)
var item = collListItem.itemAt(0);
var profile = item.get_item(‘Notes’);
var pictureUrl = item.get_item(‘Picture’).get_url();
var userImage = document.getElementById(‘myImageContainer’); -> Image object
userImage.src = pictureUrl;
var profileDiv = document.getElementById(‘userProfileContainer’);
profileDiv.innerHTML = profile;
