at QSOnet / CQ100 you may add a photo as an avator to your comments at the forum , this can be done at your profile page .
But it seems to me that is not your question but it sounds as if you refer with your question to your page at qrz.com .
CQ100 has nothing to do with QRZ.com beside clicking on a call opens your browser and you get the page displayed of QRZ.com .
If you want to add a photo or more details you have to go to www.qrz.com and read their information how to do that .
Also you may go to the forum of qrz.com.
A quick guide to do :
go to your side at qrz.com , log in with call and passwort and then go to more details , hit the button "edit record " and then a page comes up where you have links to add a biography , photos etc .
For any further help please visit the qrz.com forum .
