How do you upload pictures? Where is the attachement section?
You have to click "Go advanced" under the text box, and the upload photo option is in there. Just click "Manage Attachments" under go advanced and you can do it there.
if you are starting a new thread just use the paperclip icon at the top of the box, near the font tools.
Otherwise, just reply, but don't use "Post Quick Reply" and use that same paperclip tool.
That tool isn't there in a Quick Reply box.
MAke sure your photos are saved in jpeg format and less than 195kb in file size.
