thx for the challenge

amazing, learned much about jpg

dimension of an image are should be the same + hexeditor and rapid table

If you found Mercedes pic then it's not correct way of your thinking ;)

Tips: The flag is 'outside' the pic, but it still part of the file. Think about dimensions.

I suggest use CyberChef and HexEd

Incredibly helpful.

everything is hex and focus on resolution

thanks for the challange, i've learned a lot with hex editor

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)

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.

Need to read more. Specifically about how does JPEG stores its dimensions.
