回複：I am learning how to post a pic and a song here!

With the link "http://i19.tinypic.com/2cpc2fo.jpg". Left click "編輯助手", then left click "圖片 " on the window of 加貼編輯助手. Click "Ok" if you do not know the width of the picture, then click "OK" again if do not know the height of the picture. Now paste your picture link, such as "http://i19.tinypic.com/2cpc2fo.jpg" to the long narrow space and click "OK". You will see some source codes have been generated in the window. Copy the codes to, say the reply window (here I am writing). Click "send". That is it.
