Newbie here

I would like to upload a custom pic. The dimensions of my pic is quite huge. How do I put it here? 

Any help will be much appreciated. =) 

To upload a custom avatar photo, go to 'My Account'. At the bottom of your current image, click 'Change Photo'. Under 'Custom Profile Photo', click 'Choose File' and you can select an image that is stored on your computer/device. Click 'Save' once you are done and your new photo will be uploaded.
