Tongue How to achive image transparency on Kindle

Hi - I wondered if anyone could help me with images with transparent backgrounds on Kindle.

I'm pulling my hair out trying to find a way of reproducing artistic line separators without the 'white box' when e.g. a sepia or black screen background is not used. I've seen it done - for example, if I use one of Draft2Digital's templates which includes line art, there isn't a white box.

I've read that the latest version of Kindle supports transparent GIFs, and that GIF is the format to use. Yet whatever I've tried, they still appear with white boxes after MOBI conversion. Is there any way to format GIFs so that transparency will be preserved in a MOBI file?

If not, how is e..g. Draft2Digital's line art doing this? What format does it use? I've read that it's possible to create a custom font using a couple of characters (e.g. # and -) for some quite large graphics, and embed this as a custom font in the word file, which gives both transparency and a fallback to these standard font characters if a reader can't recognise the custom font. But I haven't found any description of how to do this (particularly for a font with only two characters, both of which don't fit into a standard font-shaped square (even using dedicated e.g. Adobe Illustrator, which I don't have).

Any help much appreciated!! :-) Thanks in advance ...
