You can upload a photo from the first page of the site – Click the button which says ‘Get your CLC card now’. You must have entered your birth ‘certificate’ and taken ownership of your ficticious name (legal fiction) FIRST. Only when you have done all three things can you order your card.
If the photo is for a clc card, go to the home page, scroll down to the bottom right where it says ‘get your clc card’, click on it, then it takes you to another page where you can click to order a card, the form has a browse button where you upload the photo. Please note its a passport sized photo.
