Hi WhiteView,
I'm a newbie too, started stock photography a few months ago. The first site I uploaded to was Big Stock and they were the last to start selling.
For some reason images there have to 'mature' a few weeks.
Once you get your first sale, others follow pretty soon, you'll see
Welcome to the world of micro stock!
It is an enjoyable adventure and I hope you'll get a lot of fun out of it
Best of luck,
Anna
