Anyway, as a challenge to others on the list: write a one-liner that splits an "image" like ["abcd","efgh","ijkl","mnop"], interpreted as

abcd efgh ijkl mnop

into the list of images:

[ ab ef , cd gh , ij mn , kl op ]

It's just an additional 'concat' in my solution, isn't it? Ah, you mean without the 'split' helper function?
