How can I view locations of layers in PSD files without photoshop on osx? I have some PSD files I had produced, but I don't have the positions of the layers aka images that were produced aka buttons etc.

I don't have photoshop.

I have tried gimp and pixelmator, but they don't show the coordinates of layers.

I have google how to do this for both of these packages, I can find the cursor position if I hover over the layers, but this isn't exact.
I have no experience with this, but I found a script that may help you.
