I'm not Amber, but when you post a reply, underneath where you type there is another box title
'Additional Options', just like on YT. Click on
manage attachments. Another box will come up, click on
browse and find the picture(s) on your computer that you want to post (make sure they are the right size) and then click
close once they have been uploaded and then click
submit reply.
If you know how to do an avatar or pictures on YT...it's the same here.
I'm usually not good at explaining things, but I hope that helped.
