Want to become a PowerPoint PRO? Take my premium course: br br In this lesson I will teach you, what would be the proper method to lockdown layers in Powerpoint. Sadly, we don't have an option for that like in photoshop or other graphic design softwares where we simply click on a layer to be locked down and we can't click it any more. Here, we have to use workarounds using Slide master, layouts, adding the images or objects there, and then using the layouts within powerpoint.
