Carousel allows uploading collections of images together as a single group, which provides an easy to setup and manage workflow from presentation programs like Microsoft PowerPoint and Apple Keynote. Carousel cannot upload and display these presentation files directly, within each program the presentation needs to be exported as images.
Exporting from Microsoft PowerPoint 365
Open your Presentation in PowerPoint
Click File → Export → Change File Type → then select “JPEG Files Interchange Format (*.jpg) → Save As
Select a location and press the Save button
When asked which slides you want to export select “All Slides”
Navigate to the location you saved the presentation to, there will be a folder with the title of your presentation which now includes all your slides as images. Right-click the folder and select Send to → Compressed (zipped) folder.
Once you have your .zip folder skip down to the Importing into Carousel section.
Exporting from Apple Keynote
Select File → Export To → Images…
Ensure the Images option is selected, the all slides option is set, and that the format is JPEG (High Quality) and click Next.
Give the export a name and then press Export.
Navigate to your folder, ensure all slides have saved, then right-click the folder and select “Compress Items” to create a .zip of your presentation.
Continue to the Importing into Carousel section.
Importing into Carousel
Log into Carousel, navigate you the zone you want to display your presentation in, click “New Bulletin” followed by “Uploaded.” Drag-and-drop or navigate to your .zip folder created earlier.
On the Change Bulletin Schedule dialog that pops up select Cancel.
By default all your uploaded images will be selected, so enter the Actions menu and click Group.
At the Actions menu again select Change Schedule then click Change Schedule in the dialog.
At this point your bulletin group will be active so click the Active filter to see the group.
Optionally, you can open the group and rename it.
Your presentation is now uploaded in Carousel and the group itself can be managed with bulletin actions for quick changes or deletion.
