I remember when I was getting my first steps on Dremastime. I was not sure how the site is working.
At first I upload one photo and wait a hole twenty one days to see that it get online I was so happy for that and upload more photos and I was first measure up wit rejection. It was very painful but still instructive. After that I search the stock to find some advices and interesting information how to make photos, what to upload and how that is working at all. Now after while I think I know much more about the site, community and about making good images. I learn a lot with Dreamstime, thanks to all of you.
My tip for newbie is do not be shy to search DT for advices and ask questions on forums, there are lots of useful information here that could help.
