You can edit your presentation slides at any time:
Click on Explore > Presentations to see the list of available presentations. You must be logged in to see your presentations.
Under My Presentations, mouse over the presentation you are interested in. You’ll see 3 icons to the right of the presentation name: Edit Presentation; Edit Presentation Properties; and Delete Presentation.
Select the first icon Edit Presentation, to be taken to the LUNA Workspace where presentations are made and edited.
Your presentation should open in the LUNA Workspace. If it did not, then simply expand the Presentation Panel and use the presentations pull down menu to select the presentation you want to edit.
You’ll see the slides for that presentation in the Presentation Panel with the image(s) from the first slide appearing in the LUNA Workspace.
Click on the slide you want to edit in the Presentation Panel. The image(s) from that slide will appear in the Workspace and ready for you to edit the layout of that slide. In addition to just re-arranging the layout of the images in that slide you can also add more images to it.
Click on the Save Slide icon when you are done editing that slide. Be sure to save your changes each time you edit slides.
To delete a slide click on the Click to delete slide icon below the preview of that slide in the Presentation Panel.
You can also copy a slide by clicking on the Copy icon beside the Delete icon. This new copied slide will appear as the last slide in your presentation. By copying a slide you are simply making a copy of it, any changes you make to the copied slide will not be reflected in the original slide.
Using the Click to move this slide over to the left or Click to move this slide over to the right icons in each slide, you can then move this copied slide to your desired place.
