image-merger

Bash script for merging N-images into 1 image - horizontally, vertically or in Matrix (2x2, 2x3, 3x2, 3x3)

Images in convert folder can have random names, but only .jpeg extension is supported.

Images can also be named like 1.jpeg 2.jpeg 3.jpeg, to give custom order of merged images.
