In DW8, I add the following to the insertbar.xml:

<category id="DW_Insertbar_My" MMString:name="My" folder="My">
<button id="My_feature" image="My\my_feat.gif"
MMString:name="insertbar/my_feat" file="My\my_feat.htm" />
</category>

Instead of displaying the my_feat.gif icon, the Insert bar displays only the
Object/generic.gif. Everything else seems to work.

Why is it referencing the wrong file?
