Do you want to give your read-only users an easy way of creating a collection based on selected assets (e.g. for creating a PIN code)? Or do you need to provide all assets related to a given asset? Both use cases are covered in this plugin.
Using the context menu "Create Collection" will prompt you for the name of your new collection and then store it in your personal collection. This requires a dedicated root node where personal collections (based on the username) will be created and given the appropriate permissions based on a given role automatically.
When using the menu on a single asset, the dialog will also ask which relation types (e.g. only images placed within the InDesign document) should be considered for the asset relations selection.
To automatically delete the object collections after a given time, we recommend our "Auto Delete Task" plugin.
