to post photos within a thread or post scroll down below the white box where you enter a reply and you will see a "Manage Attachments" button...click on that and you will see how you can upload an image
for your profile, click on the "User CP" link in the green navigation bar near the top of the site...once on that page, you will see different links on the left hand side. you can choose "Edit Profile Picture" or "Edit Avatar" or "Edit Signature" etc. and upload images that way
