Fixes jpeg identification
Adds pathFromSrc helper

This returns the dynamic parts from a file based on a config
source string/array (basically the * parts)

['/test/**/*.jpg'], 'test/abc.jpg' => 'abc.jpg'
['/test/**/*.jpg'], 'test/def/abc.jpg' => 'def/abc.jpg'
Replaces pathToGlob function with the helper version
Replaces processImageFiles output path generation

This uses the pathFromSrc helper to generate correct output paths
