That's crazy

Overthought this and wasted a long time.... But in the end acquired yet another skill.... Just read comments and understand file format. Is easy.

pay attention to the length of the file, and think about changing one of its dimensions

IT is very easy only if u know the trick but it must not be in easy section

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.
