Actually, the sprite.png file from the editor directory is all you really need to upload (to the custom skin editor directory). I ran into this on a client's custom skin and that was all I had to do to fix it for the custom skin.

@Boofo : can u post the screenshot / where I can find it in FTP/File Manager ?
btw, I din use any custom images in my theme. Have only custom status icon
My site is collegers.net -

images/editor/sprite.png

I was able to find the image path.
Where to copy the sprite.png ??
I created the theme in syle generator.
