As all the colors are grayvalues with R=G=B I thought at first, I can extract some sort of translation TABLE and was also encouraged by the fact, that each value occurs exactly once in this table. But sadly I wasn't able to translate anything into something useful with this table
I also tried to change the color palette but the only improvement I got by that was a more colorful noise...
I found a few recurrences in the imagedata but couldn't find a way to do anything useful with it - there seems to be a familiar header in the binary but i don't know how to get rid of the mess in between...
Another dead end was the fact, that the image is stored in interlaced form, but my attempts to use this somehow didn't lead anywhere
<!-- oh, and this is NOT a repeat of 14 -->
Is there more information in this hint, besides that you shouldn't do the same as in level 14?
Should the brightened area in the jpg show anything else as a zigzag?
So to sum it up: I have no idea what the hints in this level want to tell me and don't know what to do with the data
