the flag is outside of the pic, try to find it. another hint: dimensions, dimensions, everything is in dimensions.
COOL
learned lots of stuff
Tips: The flag is 'outside' the pic, but it still part of the file. Think about dimensions.
I suggest use CyberChef and HexEd

Sooo cool! Learn a lot about jpeg.
I had to fight my way there.
I don't think this should be in the easy section though
Any hint? several people (me included) seem stuck. I have read quite a bit about the jpeg specification, found something about blocks, but nothing helped so far.
This challenge really pissed me off, so i gave up on this challenge and after a month i thought let's give it one more try then after a few searchs on how hide data in image dimensions i found this blog which was really helpfully, and finally i solved this problem. (Also used hexed.it website)
