You have to find out where the white box is coming from. Off the top of my head:
--white parts of non-transparent image in non-white page, need to fix image itself (assuming either <= 256 colors, or alpha channel in browsers that support it)
--image margin non-zero on white-background page, needs CSS work --image border non-zero with color white, ditto --image padding non-zero if background-color of image div (or equivalent) is white, ditto
--(rare) if image is a link, browser supplies border and/or text-decoration unless told not to

It better not be jpg, since last time I looked, the format didn't support transparency :)
Well, you can still fake it-- I've had to, when it's a choice between that and a full-color png with alpha channel*-- but you have to remember to change the image again if you ever change the page color.
