Please note that you may have to wait a few minutes for all your images to appear in your group.
Your personal groups will appear on the left side of the page. Click on the title of a group to open it. Reorder images in a group by clicking and holding on the title of the image (below the thumbnail) and drag the image either to the right or left of another image. To delete an image from a group, click the "x" on its upper right corner of the image.
Export images into a PowerPoint presentation by opening an "Image Group" and clicking on "Export to PowerPoint". The PowerPoint presentation will be emailed to you. Check your email for the message and download the PowerPoint from there.
