Hi TexasMusic,
Sorry for my misunderstanding.
Based on my test in an IPad, it offers some quick editing function and can not make a photo transparent as a background image in PowerPoint iOS.
For complete function, I suggest you use Windows or Mac.
If you just want to use your IPad, here is a workaround:
Insert a transparent picture(you can use some third-party software), then click Picture>Arrange>Send to Back to set the picture as a background.
Given the situation, I suggest you submit this idea via UserVoice or vote for this similar idea submitted by others.
Thanks,
Cherry
