I’ve tried saving some infographics as an image, but the image isn’t formatted properly. I used the 10 plagues infographic, and parts of it had a gray background and the graphics were surrounded by white squares and lines. The gray areas are transparent: when you insert them into a presentation, you should see whatever is behind the image in those places. The white areas are a problem with the resource. I’ve reported it to the group who is in charge of this resource, and it should be addressed in a future update. In the meantime, if you put the image on a white background, it should appear just fine.
