Transparent Image over a Button

[ISI360]

Hi!

I am searching for a way to display a transparent image (or Icon) over an Button. And the image should always stay on top.

Here is what i have so far:
At script start the picture is over the button..but if you move the mouse over the button it overlaps the image.
And if i add $GUI_ONTOP to the picture, the transparency is gone

Maybe someone has an idea..

Thanks in advance!

PS: Thanks for moving!

Does this help you?

Hmm sadly no. The image in this case should not "be" the button. It should only stay over (and beyond) it.

I tell you the "background" of this stuff. Of course it´s about my ISN AutoIt Studio. Here i am using little icons in nearly every buttons.
Thes icons are set to the button via an ImageList ($BCM_SETIMAGELIST), which works very well and as it should.

So as you may know, the ISN also uses a Skin System. (The USkin UDF. I know its dead and buggy..anyhow i think its the best skin system available for autoit at the monent)
And when USkin is enabled, it kills every Icons on Buttons which are assigned thourgh an imagelist. (Its a bug/error in Uskin)
And ever "Add icon to button"-code i found at the moment adds icons with imagelists.
So now i am searching for a way to restore (or build around) with something to recreate those icons in the buttons.

I tried _GUICtrlButton_SetImage, which works with USkin...but with not text possible at the same time. 
And my other idea was to simply "draw" an icon over the button which should stay over there. Which brings me here ^^
