To attach a file to a task tap the + icon next to the Attachments section in the edit screen.

You can choose to attach from Google Drive, photos on your device, record new audio, or take a new picture.

Tap the attachment name to view it.

If the file is an image or audio file you can preview it directly inside the GQueues app.

Other types of files will open in Google Drive, if you have the Drive app installed, or in a web browser if you do not.

On the edit screen you can remove an attachment by swiping left on the filename.
