This is my first time uploading photos to your site and as a new contributor i didn't know how important is the included keywords in the photos.I send you a batch of photos before i understand that completely and now my photos has very few and not so accurate keywords...i wonder if its possible to delete all of my photos and re-upload them now which i did some serious work on the keywords and titles ? (about 280 photos) if this is possible i will save a ton of work fixing this problem on your site,one by one photo,so its a very important issue for me now since i didn't do it properly at first time.thank you for your time reading this
The keywords are useful for the users who search for the images on Adobe Stock. So when they enter keywords in their search Adobe Stock matches them to the keywords entered by the Contributor while submitting images and displays the results.
In case you wish to edit keywords or add new ones, please refer Is it possible to edit keywords after acceptance?
