Uploading your files to Shutterstock keeps getting easier. They just upgraded the Content Editor to make it faster and more powerful. For a limited time, you can continue to use the Batch Editor or the Legacy Editor, but you should switch soon, as those tools will be phased out.
With the new content editor you can:
Add titles, keywords and releases to several files at once, or just 1 at a time.
Quickly add and delete keywords.
Undo and redo changes.
All of the best features from the Batch and Legacy Editors were also preserved:
Copy and pasting keywords
Tabbing through fields
