Comment on Show HN: Embed your source code in PNG files

Cool. But something I want to know is: what are the limits of the text chunk in PNG? I just browsed the specification[1] but there was no mention of it.

It's also interesting to me that the spec says that the viewer should give the user a way to look at all the textual parts of a png (there are three), although I've never seen this offered.

2GB like all the other chunks.
