You can upload a pic into your profile (right now yours is the same as your avatar).
As I look down at the Additional Options beneath the message editor window as I reply to your message, I can see an Attach Files option (Valid file extensions: bmp gif jpe jpeg jpg png txt) and a Manage Attachments button. But methinks attaching (uploading) a file puts extra load on the AW server.
These days most folks have a Photobucket.com or Tinyurl.com or similar account and upload pics there. You only have to copy/paste the http URL between
tags to display a pic in your message. This method doesn't put extra load on the AW server.
e.g. do this,
...I've added extra spaces so you can see the IMG and /IMG tags. When the spaces are removed, the board will action the tags and your pic should display:
...Dammit, beaten to the punch by alleycat,
again.
