One idea would be to publish the user's avatar via Personal Eventing Protocol as described in XEP-0084: User Avatar
Another idea is to update the image in vCard and then send update notification via XEP-0153: vCard-Based Avatars
For the user's hour (I guess you mean timezone?!), you can use XEP-0202: Entity Time.
Afaik, you are using aSmack?! Still don't know why you ask your questions in the Openfire forum, then.
All three are client-side protocols and all are not implemented in Smack (except PEP I think), so you have to do it yourself.
