Corrupt PNGs unreadable - or are they?

Post by Danny »

This is very weird. I was sent 2 PNGs via email, and they arrived in unreadable condition. Now the funny part is, that the thumb-nailer was able to create thumbs for them, but if i tried to open them it xnview tells me there was an "error opening file".

So, why can't i open those pictures when building thumbs is possible?

P.S.: Unfortunately i can't send you those images since they contain personal information.
Get the bugs fixed, THEN start adding features. It sucks, but someone has to do it.

Can you open the images if you deactivate the Ignore read errors setting in Tools » Options » General » Read/Write » General?

You may also want to examine the files with TweakPNG (File » Check Validity).

Sorry for my late reply. I should have tried that, but i've already recovered those files through other means.
