wolf11th: i found the img of this button and replaced all the img under this name. However, it still show the old img. i really don't know why. can someone help? Hi wolf11th, Below is an example to tell you how to change the ico of 'InsertImage' button 1. Open file "CuteEditor\Configuration\AutoConfigure\Default.config" 2. Find section below <item type="image" name="InsertImage" imagename="eximage" /> 3. Change the imagename to your image name. If you image name 'hellow.gif', just change to <item type="image" name="InsertImage" imagename="hellow" /> Note: your image need to put in folder "CuteSoft_Client\CuteEditor\Themes\Office2003\Images" If you use another configuration file or another Theme, please edit the appropriate file Regards, Ken
