Hello, I completed this using paint, but i am curious as to how people completed this using hex editor. I have it open in XVI32 and the representation is very different from what one might expect (if one does not really know what to expect). How is the image represented in the hex editor? Is there some kind of transform or am I way off? Just interested to know. Thanks!

Using Hex Editor lead me to find areas where the hex code had some differences.
Instead of having a full RGB62/62/62 image there are some places where the 62 is replaced with 61, but I don't know how to find if it's the R the G or the B and what to do from that point on. Any tips? :/

Finally solved it using Hex Editor.

I don't get it how you guys say you've only used paint to figure it out...

I'll probably look dumb, but... I really don't get what to do. I've opened the file with HexEdit and saw where was the difference but I still don't get what's the answer. I don't know if any hint more revelative would be considered as a spoiler, but if it is just pm me please. I really don't get it at all. damndamndamn

EDIT : Got it. I used Paint.NET, but most of basic picture editors would do the job.

I don't think I'm getting the same image as everybody else. Opening the file in a hex editor indicates that the entire colour table has the same value, and there's not actually any information at all in the image, which is clearly wrong given the comments here.

EDIT: Please disregard, apparently I just failed to see any abnormalities when scrolling past them a few times. Should also point out that for whatever reason, the obvious function to do this in GIMP doesn't work and misses the message.

Not a spoiler, but it shows that you DON'T do it this way.

I initially opened in a hex editor and thought that the offsets of the different values some how linked to the ascii value, and went through a convoluted process of writing a PHP script to go through various combinations to get back string values.

Having worked out the correct answer, I feel so dumb.
