I wrote a blog over a month ago and it seemed to be well received. Here is a follow up with some more tips:
a) Take a set of submissions and rank them in terms of whether you think they will be accepted or not. Label the ones you feel the best about with '1', and the ones you are unsure of with '2'. See how close you come to matching the reviewers. I find I often have a 'feeling' that something won't be accepted - and then it isn't. You need to learn to trust this feeling and keep your acceptance high.
c) A classic rule is to only submit one image from a series to ensure you don't get a large number rejected at once for the same reason. Especially when it is fixable (bad contrast, noise, etc.).
The most "popular" section you can't do much about. The editor's choice section appears if you get some editor's choice images. This is a worthy goal of anyone as it means you've submitted something that catches the editor's eye. The exclusive row has a selection of 9 of your exclusive images. If you are exclusive with DT you can't do much about this either, but if you are not you can chose up to 9 select images and make them exclusive - they will then always be visible on your profile page. Finally, when you use models the first image uploaded tends to be the one displayed. This is your chance to get another great image on your profile. Choose wisely for the first image of a model!
Start by uploading a fixed amount each month for 10 months - say 10-20 photos a month. Then, once you get to 10 months aim to upload 10% of your portfolio each month to ensure your sales continue to grow, not slowly decline. So after you get 100 shots you do 10 the next month, then 11, etc. Doesn't seem so bad at first, but after a while you're uploading twice as many photos a month! I'm at 610 uploads now and my goal is to add 61 pictures this month...
4. Finally, a few more common questions gleaned from the message boards:
In the account stats 'Downloads' refers to the number of photos you've bought. You can only view your total sales on the profile page or in the Management Area. The profile page updates the next day for sales, but updates right away for new uploads.
Credits can be obtained for writing a blog, such as this one. Don't be surprised if you write a blog and discover you've earned a credit!
Once you get a payout and request it, your total revenue will drop by the amount requested until you actually get the payout. Then it will jump back up to show your total earnings over time.
New uploads don't appear in the search results right away. As well, if you edit keywords or titles it takes another day or so to see them in search results again.
When uploading and you get rejections, don't take it to the message boards. You can e-mail support directly using the contact us link at the bottom of the webpage. Don't abuse this privilege as the reviewers go through tens of thousands of images a month - but don't hesitate to ask if you don't understand the rejection reason. If you do contact support note that when you submit certain types of questions they give you some frequently asked questions and responses - you have to still click Submit one more time to actually send the message.
