Having pre-designed backgrounds with areas for hotspots on your slides is what we ideally recommend - but you absolutely don't need to! You can set any background you like, or stick with a blank background. Whichever option you'll choose, you may at some point need to assign a background image to a slide.
If you'd like to start from scratch on your own - when creating a new showcase, select "New Showcase from template" and there you will be able to use one of our handy templates to begin. These already have slide background images in them which you can replace.
Here's how you set a slide background:
- On the Home tab, click ‘Edit’ under the showcase you wish to set a new background for.
- Select ‘Background’ from the menu above your showcase, and click "Choose background". If there's already a background there (like from a template), choose "Replace".
- Choose an image file from the file library, or upload a file from your computer.
To get the image to fit exactly, you'll need to take a note of the ideal slide dimensions, which are on the "Background" panel next to the little "i" symbol at the bottom. In this example, it's 2048 x 1536 pixels. Don't worry if it isn't exact however; the image will still be centered as big as it can go, and any extra space will show up black.
To remove the slide background, click the ‘Remove’ button from that same 'Background' panel. You can then set a different background if desired by following steps 2 & 3 above.
You will need to publish this change in order for it to take effect.
