Re: Transparency in images

Hi Lora,

There's nothing in the standard that prevents you from using transparent
images but support for transparency will vary from one reading system to
the next. If Scribd has built it's own epub reading system, then it's
likely this is a quirk in the reader and your engineering team will need to
take a look if you want to support transparent images. If you are using
someone else's RS - I would reach out to them and find out what they
support.

Best,
Rachel
