On the left you see the tabs for attendance etc, there's also a tab called my account where you can change your personal info. Uploading an avatar is one of the options.

that's where ur wrong i dont see it at all click and checked on all the Tabs :/

The My Account one should be all the way to the left of the tabs, reached using the scroll arrow?

i see it all but i dont see the place where i upload my avatar =.=

When you click on the My Account icon then please click on My Information link. On the next page enter your password and click on the Send Confirmation button. Get the confirmation code from your registered email address and put that in the box then click Submit. On the next page is the facility to upload your Avatar.

omg click on your name on the left hand side, above the olives!
