Ren'Py How to make circle imagebuttons? [SOLVED]

[TheBardOfAllTales]

Hi everyone,
I'm trying to make circle imagebuttons, but I only get squares with the circular image I use and a black background.
This is an example:


and this is the code I used for the phone Imagebutton:

frame:
    xpos 1060
    ypos 10
    imagebutton:
        idle "imagebutton-phone.png"
        hover "imagebutton-phone.png" action Jump("thirdlabel")
        focus_mask True

what am I doing wrong?
Thanks for any help

I'm an idiot... I was creating a "frame" for each imagebutton...
removing "frame" solved it!

The 'frame' is drawing the box and black background around the imagebutton.

Thanks Epadder, I realized it after staring blankly at the code...
By the way, I love Adam and Gaia!!!
