Sample outputs: |

|
| 183 |
This is the base structure. The variation is the image that is marked as {Image}: |
| 184 |
<td><div class="TB_Button_On" title="Smiley">{Image}</div></td> |
| 185 |
<td><div class="TB_Button_On" title="Smiley"><table cellpadding="0" cellspacing="0"><tr><td>{Image}</td><td nowrap>Toolbar Button</td><td><img class="TB_Button_Padding"></td></tr></table></div></td> |

Strip - IE version: |
| 191 |
<div class="TB_Button_Image"><img src="strip.gif" style="top:-16px"></div> |
