Why is my texture showing pink in render view when the image path is correct and cycles is the render engine? I am having the exact same issue as discussed in this thread:
 Why does this texture appear fine in material view but appears pink in rendered view?



The image file is not missing - I have used "find missing files", as well as assigning and unwrapping again. The image shows up in the 3D view but is only visible as pink in the render view. I have exported the file from PS as a TIFF with alpha. Is this a bug or am I and Sarsha W doing something wrong?

I'm running Blender 2.78a on a PC.

BTW, I've been going step by step from this tutorial, and the alpha channel texture is the only one with this problem
Rick Riggs suggestion to pack the image file:

Blender-> File -> External Data -> Automatically pack into .blend

worked like a charm. Once I checked that, the texture was applied to the surface.
