libpng warning: iCCP: CRC error

[jaycdave88]

I am running into: ibpng warning: iCCP: CRC error and I cant seem to find any documents on what this error means or how would I even go about attempting to fix it.

Full stack error:

I know this was a while ago but pngfix, which is provided by the libpng project, might help.

@allanlewis How so?

This was two years ago 😂
I suppose I thought that pngfix might fix a given file such that this warning isn't emitted; I don't remember, sorry!
