Images are not getting optimized. It keeps saying Result: 1 ( I'm assuming that this means it fails ) on all images.
My images path is set correctly in the config files and I'm using the latest version of optipng ( 0.7 ). My OS is Ubuntu.
Also: optipng works fine via the terminal. It only fails within the build script.
I'm closing this as I can't recreate on Precise Pangolin
