so let's say for alamy contributors, we should just opt in those files that are not available in alamy?
does it mean our files that opt-in in alamy will appear under alamy search engine as well?
You just should release the photos which are not there yet. This is not only for alamy. This is also for AGE/THP and other partners. Except Fotofinder and APIS, because every agency has own channels for own costuimers there...
Correct, the best is to opt-in only thoose files for alamy that are not avialable at alamy yet. So you can prevent double releases there.
I´m not sure if i understand you second question correctly, but all photos you are opt-in from zoonar to alamy are really going from zoonar to alamy. To have sells at alamy they have to be placed in the alamy search engine...
