### What should this feature add?

Bulk actions for Image Board

Two ideas come to mind to make image boards more useful:
1. Export selected images
2. Export all images
3. Export selected metadata to CSV / workflow
4. Export all metadata to CSV / workflow

Just thinking about making image boards more useful. I'll use an example to demonstrate the point: Say you've put together a collection of images into a board - there's no way of exporting that. It still needs to be downloaded 1 by 1. Bulk actions that apply to a board would be ideal, such as download the board of images, or export the meta data for each image to a CSV.

### Alternatives

Using the Retrieve Images from Board node and wiring this for output.
