Description

I have these 2 images, can you make a flag out of them? scrambled1.png scrambled2.png

Hints

1. https://en.wikipedia.org/wiki/Visual_cryptography
2. Think of different ways you can "stack" images

Approach

I downloaded stegsolve. Make sure Java is installed.

I opened the stegsolve jar file. In the jar file, I opened

File > Open(O)

I then overlayed

on top. Analyse > Image Combiner

I went through a bunch of different adding methods before ADD finally worked.
