It sounds like you get credits for voting on paired up images. But I didn't dig too deep as it stopped letting me do anything unless I linked to Facebook. I hate it when sites do that.
I signed up, cherry picked a dozen pics outta my archives, uploaded 'em, and won a bunch of awards.
From the about page: What are “Credits” and how do I earn them?
In order to make sure that every image gets enough votes we require that you spend 10 credits for every image that you upload. You can earn one credit for every ImageDuel you complete.
It's not really much of a site that will really push you unless you're unbelievably competitive by nature and have to be Number 1.
You get awards for percentages, and it's not really much of a challenge.
With your stuff, that's what it would be......I looked and you'll rack up the points....you have already!
Yep to me it made no sense, in the instructions it say's you get credits/points when you win things, well I won some things and got points and I can see no credits/points. I even looked into whether you had to 'buy' credits/points' but naught there either.
Okay so been playing around with the site, and I have to say, I am actually enjoying it. I really like their voting system, they take 2 photographs and it goes into duals with the same category, you click on the one you like. I am really liking that, as you can usually tell straight away which one is better, but at the same point, you are learning from it as you can visually see why one is better than another, I have picked up a fair few tips on this type of voting, I am enjoying it!
