If you want to layer your images, add cut outs or download a design with a transparent background such as a Snapchat geofilter, you can easily find images in the Design Wizard image search.
Start by searching for the image that you’d like to put into your design e.g. woman singing. When you’ve entered your search, you can narrow down your search results to transparent images using the 'transparent' button located under the search bar as shown below:
When you click on the transparency button all the images that appear in your search results, displayed in the sidebar will appear without a background.
