I'm an issue. Auto-Blend Layers error: The parameters for command "Trim" are not currently valid. Trying to blend 2 faces, images are JPEGs and I'm new to PS. Using Photoshop CC Adobe Photoshop Version: 2017.0.1 20161130.r.29 2016/11/30:23:00:00 CL 1099099 x64 on Win7, SP1. Any help would be greatly appreciated. Thanks much!
