There is a particular icon library that I really like.

Now, I have downloaded the package that has the png files inside (I know the ico files are there, but I want the png files).

However, about my Windows 7 computer tells me that about 1/3 of the png files are corrupt. I usually use XnView to view the files, and it won't display the "corrupt" files. I've tried other editors and viewers and I get the same issue.

Now, the png package was originally designed for Linux to be an OS-icon-package for the entire system, so I figure the png files were built in Linux.

So, is there a way I can "fix" the "corrupted" png files for my Windows 7 computer? Maybe when the files were created there was some bit that was off-colour or something?

Any clues?

[edit]

I have read in this thread that the "corruption" could happen during the extraction process. I did all the extraction with 7-zip. It was a zip containing a tar. I will try another extractor, but I don't think it will make any difference.
