ok.... 

 ( me = noob)
say for example...
Here is the generic lay.file...<!-- bezel.lay -->
<mamelayout version="2">
   <element name="bezel">
      <image file="mame.png" />
   </element>
   <view name="Bezel Artwork">
      <screen index="0">
         <bounds left="140" top="0" right="500" bottom="480" />
      </screen>
      <bezel element="bezel">
         <bounds left="0" top="0" right="640" bottom="480" />
      </bezel>
   </view>
</mamelayout>
Ok...now here is the orginal .lay file for say 1943....<!-- 1943.lay -->
<mamelayout version="2">
   <element name="bezel">
      <image file="1943.png" />
   </element>
   <view name="Upright_Artwork">
      <screen index="0">
         <bounds x="1017" y="663" width="1950" height="2600" />
      </screen>
      <bezel element="bezel">
         <bounds x="0" y="0" width="4000" height="3969" />
      </bezel>
   </view>
</mamelayout>
What and where does the exact "paste-ing" go? I want to make it where whoever can make the choice of what bezel to use....I'm sorry for being a dumba%%...I'm not thinking straight today...
