Transparent form with background image

Question

I am trying to set the form's background as invisible as I want the background image to be the thing that has the transparency.

I have used multiple background colours; - lime, magenta, red, white with the same transparency key but they all give me a horrible result. You can see that I have set the backcolour to be yellow, and the transparency key to yellow but at the top there is still yellow

I have also used

SetStyle(ControlStyles.SupportsTransparentBackColor, true);
this.BackColor = Color.Transparent;

That didn't work either and neither did

protected override void OnPaintBackground(PaintEventArgs e) { /* Ignore */ }

Does anyone have a way that I can do this?

You want the background picture to be transparent by any percentage? — Ali.Rashidi, May 25 '14 at 20:03
No, I need the form to be invisible so it's just the background picture and buttons visible (see in image, I need the yellow gone) — user2913720, May 25 '14 at 20:06
as far as I know it is not possible with transparency. You'll need to create graphics — Ali.Rashidi, May 25 '14 at 20:14
I have a background image that has transparency, I have tried removing the background image from the form, then adding a picture box but that didn't work either — user2913720, May 25 '14 at 20:17

I have already tried those, still give me the same result (only partially gone) — user2913720, May 25 '14 at 21:00
