If I remember correctly, the 89a format supports transparency; the other
one does not.
If any tool can do batch conversions, it would be DeBabelizer. However, I
think it's only available on Macs. I'm not saying I know for sure this
tool can do this type of batch job, just that it seems to handle
everything else anyone throws at it. My guess would be that all of your
backgrounds would have to be the same color...
On a one-at-a-time basis, you could do the conversion in Photoshop as
long as you have the GIF89a plug-in.

Subject: Transparent GIF's
Hi Michael and All,
Does anyone know what the difference between an 87a and an 89a is?
I have been searching for a utility that can do batch conversions of
GIF's to transparent 87a or 89a. I have not had any luck.
Does anyone know if there is a way to do batch conversion of GIF's to
transparent 87a or 89a?
