Thank you. Chequer Pattern is what you are referring to. Can you please post a MediaInfo of the png events that are not working:

Clearly, that some png's that work with alpha suggests that the problem lies with the png's that don 't work.

im downloading it but i dont fully understand how it works.

And i also dont understand what im supposed to do.

sry im not very good at these things

24 bit PNGs are not.

how do i know if it's 32 bits from google? thanks.

Some sites describe the characteristics of the files offered for download, some don't. Download and check with Mediainfo or Photoshop. I usually create or acquire the image I want and add transparency in Photoshop if I need it.
