MediaStorage - be able to select an existing file

[dantownsend]

MediaStorage allows you to upload files. But lets say you want to reuse the same image for several rows, the choices are:

• upload the same file again
• copy the value from an existing row, and paste it in

Here's a very rough idea of what the UI could look like.

We add a link for using an existing file, next to the file input:

This opens a modal listing / showing each file in the media storage's folder.

When the user picks one, we use the filename from that file.
