Using a png with alpha channel

Hi

I have our logo saved as a png with alpha channel filter the white background as header image. However when I insert the image in the header the white background is back again. How do I make the white background gone.

The logo image is a JPEG file when I check your form. This is the reason why it has white background.

I suggest to save it again into a PNG file and re-upload it in the form builder. PNG files should work just fine.
