A different image for the button

Hi, thanks for your answer, but isn't the solution, because the image "editor/css/images/fck_flashlogo.gif" is different than the image that I see in the editor.

If someone can help me, please...

I did it! I have been able to change the image of the button. To do this, is necessary to modify the following image: editor/skins/silver(or the skin that you have chosen)/fck_srtip.gif

This is an image that contains all the icons of the different editor's buttons.
