Interesting, kind of like a code style checker.

This sounds like a really nice idea.

This is an interesting problem, I wonder if Photoshop or The Gimp actually do something fancy here. There shouldn't be much of a problem replacing files when the files never get bigger and uncompressed ZIPs are used (compressed would make any sense for PNGs and JPGs anyway). Small variations in file size could be compensated with some kind of padding, but it seems to me that we are approaching a point of complexity here, where we should just use another kind of filesystem, one that supports fragmented data.

The file extension actually makes a difference here, CBRs are RAR compressed archives.

I think you misunderstood the intentions here, the game was not supposed to be a demonstration of what is possible with HTML5.

The author probably just wanted to show what he does to practice his programming skills.

Yes, "I'm sorry" always carries the connotation of "this won't happen again" with it. If you are sorry all the time, it doesn't actually mean anything.

Like everywhere else the basic design principle of contrast also holds in the tone of error messages.

If you shout all the time, nobody will listen when you really mean it. Likewise, if you are sorry all the time, nobody will take your apology serious.

When there are no pictures, people will create their own images in their minds which are probably wrong. You don't want that.

My impression was that it had to do with the gamma correction of PNG images. The 4chan thumbnail generator seems to ignore the gamma correction while the browser does not.
