I had the same invalid “Portable Network Graphics” image and  “List index out of bounds” errors. I wrote a PowerShell script that optimizes all png files in my POPMedia directory. It uses the program OptiPNG. It fixes all CRC errors of the PNG files. See attachment…

To allow execution of Powershell scripts start Windows PowerShell with the “Run as Administrator” option. And run set-executionpolicy remotesigned

Don’t forget to backup your POPMedia dir first!
