FIRST

First photo with a very small size
WEBP = 190 KB / PNG = 280 KB
As far as I know, the second smaller photo is "M.I" with 19000 KB ! (one hundred times bigger)

First photo created without using any software convertor/generator, algorithms, codes, ...
Only a photo editor and text editor

My first full photo 4096x4096
(excepted entries with duplicated tiles/pieces)
without alpha channels
