Broken Image

Are we supposed to find the one byte which is wrong by hand?
I assume you know the file structure of a PNG - try following that through by hand and see if something's wrong.

Well, I found the PNG (Portable Network Graphics) Specification, Version 1.2.
[edited because DaymItzJack though I would give too much information]
But my hex-editor has no possibility to jump to a certain byte and I don't want to count up to [edited]. Do you know a good hex editor for Linux (GNOME / Ubuntu)?
Edit: The tEXt chunk is not valid, as it should contain as its first data a keyword (source). But thats more than a single byte.

You're so close 
If your hex editor has a search function it should be enough.

Some of your posts are giving away a little too much information in my opinion.

my hint: tEXt is ok, focus in another field.

isn't it Funny how one single corrupted byte can render the whole image useless. ?
