Hi Rahul,
I know, writing software is like having a baby: you'll be in charge for the rest of your life.
But, sorry, It's long time I wrote this, and I even don't know if it's still working, or the sildeshare api has so changed that it doesn't.
At present I have no time for looking at this problem, but if you or someone else will solve the problem and submit a patch, I will be very happy to introduce it in JSlideShare (and give credits to the author, of course).
Kind regards,
Lucio
