I tried to convert an EPUB file with some png/gif files that have transparent zones, and that zones turns to black color, when i convert it to .MOBI for a kindle3.

If a ebook page it's supposed to be white (usually)... Why the "transparent zone" turns black?

Is there any option that i cannot see to fix|change this?
or do i have to edit the image file manually before the conversion?

Note: I know that I can use the "Tweak epub" option and edit the image, and this is not a big problem. But, why don't to add an option to fix this, or change the default black color to white?

Sorry for my poor english
and Thanks for any answer.
