Can I use the editor to open previous galleries in order to edit them and add photos to them or can it only be used once to create the gallery and publish?
Your Editor settings are stored in the editor-config.txt file in the highslide folder downloaded from the Editor, but images uploaded to the Editor will not be stored due to server capacity. The images will sometimes remain on the server for a few days.
